Debunking the Flat Earth Myth

Since today is Columbus Day, I thought I would discuss a myth commonly associated with the man. I learned it in school, as did many others. It’s the myth that people in Columbus’s day thought the earth was flat. Highlights of American History Before 1850, for example, tells students about a conversation that supposedly took place between Christopher Columbus and Queen Isabella:1

“Your Highness,” said Columbus, “instead of going east across the land to reach India, your traders can sail west across the ocean.” “What? Are you mad?” asked Queen Isabella. “If they sail too far west they will fall off the edge of the earth!”

A more recent book puts it this way:2

Only 500 years ago, sailors aboard the Santa Maria begged Columbus to turn back lest they sail off the Earth’s “edge.”

There is a big problem with such pronouncements: no historical evidence exists to back up the idea that most people (even uneducated people) in Columbus’s day believed the earth was flat. In addition, there is a wealth of evidence that indicates no one took such an idea seriously.

We know, for example, that philosophers understood the spherical shape of the earth long before Christ was born. It was discussed by philosophers like Pythagoras in the fifth century BC3 and became widely accepted when it was championed by Aristotle (384–322 BC). He saw that the stars were different in one part of the world than the other. This indicated to him that the earth must be a sphere.4 The spherical shape of the earth was so widely accepted among philosophers that Eratosthenes (c.276–c.195 BC) used the change in a staff’s shadow resulting from a 500-mile trip to measure the circumference of the earth. He was correct to within less than 2% of today’s accepted value.5

But wait a minute. Didn’t the early church teach that the earth is flat? Absolutely not. The earliest* voice in Christendom who mentions the shape of the earth is Clement of Alexandria (AD 150-215), and he wrote:6

And how the Earth and sea their place should keep; And when the seasons, in their circling course, winter and summer, spring and autumn, each should come, according to well ordered plan; out of a confused heap who didst create this ordered sphere, and from the shapeless mass.

I can’t find any early Christian writer who even suggested that the earth was flat. Why do people think the church taught a flat earth? According to historian Dr. James Hannam:7

The myth that a flat earth was part of Christian doctrine in the Middle Ages appears to have originated with Sir Francis Bacon (1561–1626), who wrongly claimed that geographers had been put on trial for impiety after asserting the contrary.

So the church never taught a flat earth, and educated people since the third century BC knew the spherical shape of the earth. Even uneducated sailors understood that the earth must be a sphere, because they knew you that the higher you got above sea level, the farther away you could see the ships that were at sail. Why, then, did Columbus have trouble getting support for his ambitious idea to sail around the world to reach India? Because thanks to Eratosthenes in the second century BC, educated people knew how far he would have to sail to complete the trip, and they didn’t believe such a voyage could be made!

But who originated the idea that people thought Columbus would sail off the edge of the earth? It seems to have come from Washington Irving, the fiction author who wrote “The Legend of Sleepy Hollow.” In 1828, he wrote a novel of historical fiction entitled, A History of the Life and Voyages of Christopher Columbus. Apparently, he read an account of the meeting between Columbus and Queen Isabella that was written 130 years after Columbus set sail. He embellished it, and ended up producing a scene in which a “university council” argued that the earth was flat and Columbus would sail off its edge. Samuel Eliot Morison (a historian and distinguished naval officer) evaluates Irving’s work as follows:8

The whole story is misleading and mischievous nonsense…The sphericity of the globe was not in question. The issue was the width of the ocean; and therein, the opposition was right.

On this Columbus day (or any other day), when you hear someone say that ancient people (or the church) thought the earth was flat, please set them straight. Lies need to be debunked, especially ones that are taught to us in school!

*NOTE: A reader sent me an earlier quote from a Christian writer regarding the shape of the earth. It is from Athenagoras of Athens (c. AD 133 – c. AD 190):

For if the world, being made spherical, is confined within the circles of heaven, and the Creator of the world is above the things created, managing that by His providential care of these, what place is there for the second god, or for other gods?

  1. Benjamin A. Tagle says:

    Below is a link to a website that lists classical writers who ascribed to a flat earth, including a number of early church leaders who held to that view due mainly to scriptural passages (as with today’s Biblical literalists). They are in the minority, as with today’s literalists, and their views do not reflect official Church teachings. Their viewpoint fell out of disfavor, particularly after 700 CE. Certainly, the spherical nature of the earth was largely accepted several centuries before Columbus.

    1. jlwile says:

      Thanks for the link, Benjamin. The theology listed on the site is, not surprisingly, quite wrong, as the Bible doesn’t even imply that the earth is flat. In addition, the discussion of Basil of Caesarea is not accurate. Basil saw no contradiction between a spherical earth and Scripture, because there isn’t one. He simply said that the shape of the earth has no bearing on theology. There are many writers with whom I am unfamiliar, however, so it will be an interesting resource to investigate.

    2. Jonathan Sarfati says:

      A lot of those links in that contents box are broken, which is pretty slack. But the introduction shows that the author revised his view simply by looking at what the ancients said, as opposed to the thouroughly distorted 19th-century anti-Christian agitprop by Draper and White. The intro link says:

      Is it a Myth that Flat Earth Thinking Existed in History??
      Well, No!

      However, we hope to convey that a flat earth view was not the mainstream view among scholars at all, but probably had a very limited following in pre-medieval times with only a trace in the earliest medieval times represented almost solely by Cosmas Indicopleustes. Contrary to many contemporary writers, we also maintain that many Church Fathers vigorously opposing ‘pagan’ teachings of ancient philosophers were not necessarily promoting the flat earth.

      It is clear to us that flat earth belief was extremely limited and mostly pre-medieval. The spherical view prevailed and is abundantly represented in works in later medieval times.

  2. Benjamin A. Tagle says:

    There are many Biblical passages that mention “ends of the earth” or “four corners of the earth”: Deuteronomy 13:7, 28:64, 33:17, 1Samuel 2:10, Psalms 48:10, 61:2, Proverbs 17:24, 30:4, Isaiah 5:26, 11:12, Jeremiah 25:33, Job 37:3, Matthew 24:31, Revelation 20:8. These are often interpreted as poetic descriptions that should not be taken literally. This, however, presupposes that the ancient writers did not mean a literal sense.

    Other passages more clearly imply a planar earth: Daniel 4:10-11, Matthew 4:8, Luke 4:5, wherein a tall tree can be seen from the whole earth or the whole earth can be seen from a high mountain.

    Furthermore, the account of creation only makes sense in the context of Near Eastern cosmology.
    2And the earth was without form, and void; and darkness was upon the face of the deep. And the Spirit of God moved upon the face of the waters.
    6And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.
    7 And God made the firmament, and divided the waters which were under the firmament from the waters which were above the firmament: and it was so. [Gen. 1:2, 6, 7]
    8You shall not make for yourself an image in the form of anything in heaven above or on the earth beneath or in the waters below. [Deuteronomy 5:8]
    6He builds his lofty palace in the heavens and sets its foundation on the earth… [Amos 9:6]

    Here is a graphic of ancient Hebrew cosmology,
    based upon that of the Mesopotamians: [], []

    The Biblical passages make sense only in the face of Near Eastern cosmology, which is that of a flat earth formed out of the watery chaos. That was one of the problems the early church faced. The more learned church fathers took the “scientific,” spherical earth views of Aristotle and talked down their literalist brethren.

    1. jlwile says:

      You are quite wrong about that, Ben. The Bible doesn’t even imply a flat earth. I am sure that the ancient Hebrew conception of the earth was shaped by Near Eastern Cosmology, just as the cosmology of the majority of Christians today is influenced by The Big Bang. However, Near Eastern Cosmology is not in the Bible. The reference to “four corners” has nothing to do with a flat earth. As explained here and many other places, the Hebrew word is “Kanaph,” which means “extremity.” Translating that word to “corner” simply is using the “language of appearance,” which is common even today. When the newspaper reports the time of sunrise and sunset, we don’t accuse the writers of being geocentrists. Indeed, even the term “four corners of the earth” is used to this day, and no one accuses those who use it of being flat-earthers.

      Daniel 4:10-11 is about a dream. It does not even imply that such a thing actually exists in the natural world. Matthew 4:8 and Luke 4:5 describe an encounter between the Devil and Jesus. It is clearly dealing with supernatural things, not the natural world.

      The account of creation makes perfect sense in modern terms. There is no need to invoke Near Eastern Cosmology to understand it. This is why people with no knowledge of Near Eastern Cosmology can understand it perfectly.

      Deuteronomy 5:8 doesn’t have anything to do with Near Eastern Cosmology or a flat earth. It is simply telling people that they should not make idols of what is in the sky, on the earth, or in the seas.

      Amos 9:6 is not referring to a flat earth. It is part of a vision, and the vision is about God’s Judgement. It has nothing to do with the natural world.

      The early church faced no problem with natural philosophy. Indeed, that is why a flat earth was the opinion of only a tiny minority in the church. The Bible doesn’t promote a flat earth in any way.

    2. steve hays says:

      Surely ancient people had experience climbing the highest hills and mountains in their locality. But they knew you couldn’t see the whole world from that vantage point. After all, many ancient people travelled widely. Consider the far-flung travels of Abraham and St. Paul.

      They could also see that rain comes from rainclouds.

  3. Benjamin A. Tagle says:

    I think that you are reading modern interpretations into ancient writings. This is like insisting that Thomas Jefferson and Mark Twain were not racist to some degree because in our time this sort of attitude is politically incorrect. We would like to think that they were enlightened human beings, supportive of the civil rights amendment and all that, but the truth is that they were products of their day and progressive as they may have been, their worldviews would probably sound backwards to us today.

    The authors of the Bible were products of their time too, which is why they describe the commencement of the Flood as “the fountains of the deep” breaking up and the “windows of heaven” being opened (Genesis 7:11). We can interpret this as poetic language describing waters rising up from “the deep” of the ocean and falling down as torrential rain, but that is not necessarily what the ancients meant. If the heavens above and the earth below are surrounded by water as the ancients believed, then it makes sense that openings can be broken in the earth to allow the waters of the deep to flood the earth and that windows can be opened in a solid firmament to let in waters from above. This is a better understanding of why the biblical authors described events in this way rather than simply ascribing it all to “poetic language.”

    This is not to say that the Bible actively teaches that the earth is flat, only that the early biblical writers described the world as they understood it at the time. Why else would there be a debate in the early church if this were not so?

    1. jlwile says:

      Benjamin, I think you are reading your interpretation of what ancient people thought into the Bible. I would prefer to read the Bible and see what it teaches. When I do that, I don’t see any hint of a flat earth. I am not trying to think that the ancient people who wrote the Bible were more or less enlightened than we are. I am simply reading what they wrote and seeing what it says. It says nothing about a flat earth.

      The Flood description is a perfect example of what you are doing. You are assuming that the writers believed that the heavens above and the earth below were surrounded by water. They may have believed that, but I don’t know. However, I can read what they wrote and see that it says nothing about such things. We know that water shoots from hydrothermal vents at the bottom of the ocean. Those could be the “fountains of the deep.” If those fountains were all open, then the waters would, indeed, rise, just as they did in the Flood. There is nothing in the Bible to indicate that the Flood was caused by openings in some firmament. That’s simply you assuming what the ancients meant, based on what you are assuming they believed. Once again, I prefer to read the Bible to see what it teaches, making as few assumptions as possible.

      There was very little debate in the early church about the shape of the earth. This is clear from the fact that very few early Christian writers tried to suggest it. What little debate did exist was probably caused by the fact that there were some people who believed in a flat earth, independent of what the Bible says. Just as the current Bible-independent opinions of people can cause debate in the church today, I am sure that Bible-independent views caused debate within the church back then. The very fact that few early Christians wrote about a flat earth indicates that the Bible doesn’t teach it.

    2. steve hays says:


      You’re deliberately ignoring the fact that as a matter of observation and experience, people in Bible times could tell that rain came from rain clouds. Likewise, it might look as if the sky rests on mountains, but if you scaled the mountain, you wouldn’t bump your head against the sky. By the same token, it might look like a mountain range marked the end of the world, but many people had occasion to travel beyond the local mountain range.

      You’re interpreting literary notices without regard to how ancient people actually experienced their environment. Your flat earth/3-story cosmography is simply inconsistent with what people back then were in a position to know.

      This is an example of what I call deskbound exegesis. You have modern scholars who are out of touch with nature. But ancient people had to be keen observers of nature to survive.

      1. Benjamin A. Tagle says:

        This is not ‘my’ opinion. Check out this article which details how some relatively ‘modern’ view the universe: [].

        1. jlwile says:

          The article to which you link (written by Dr. Enns) is based on a two-part series by Paul H. Seely that appeared in the Westminster Theological Journal. What Enns fails to point out is that those articles have been fully refuted by a subsequent article that appeared in the same journal. The refutation is by Noel K. Weeks and appears in the Fall 2006 edition of the journal [Noel K. Weeks, “Cosmology In Historical Context,” WTJ 68:2, Fall 2006]. A couple of important quotes from that article:

          It is common to proclaim this or that element of Scripture as a reflection of views or practices of the time. The confidence with which this is said conveys to the reader that recovering what was generally believed or done at the time is easy. Often that is far from the case. If we are dealing particularly with the OT, then the problem is greater because of the lack of extra-biblical material from Palestine. One passage may be illuminated by another passage of Scripture, but it could be argued that both passages are reflections of common views of the time. Ideally, we need copious documentation external to the biblical text and rarely is that the case. Externally written material from Palestine that will illumine things such as cosmological beliefs is non-existent. The resort to Ugaritic material to fill the gap left by the lack of Palestinian material brings its own problems of being certain that Ugarit is fully representative of Palestinian beliefs and practices. Mute archaeological findings may somewhat fill that gap but material remains speak to a limited range of issues. The course of argument from mute archaeological findings to abstract beliefs is so problematic as to be not worth considering…

          Seely argues that there is a common pre-modern conception of the sky as a solid dome. Hence, the writers of the Bible must have been thinking of the firmament of Gen 1:6-8 as solid. His primary argument from the biblical text itself rests upon the meaning of raqia. The root has the sense of stamping or beating out something. Seely’s view has been contested by J. P. Holding who points out that the raqia is called heaven (Gen 1:8). Birds fly in heaven (Deut 4:17) and God is enthroned in heaven (Ps 11:4), so it cannot be conceived as a solid structure. Seely attempted to deal with this in his original article by saying that heaven is wider than the raqia. However, the proof texts that he cites for that proposition are all texts which show that heaven is not solid. Thus, they prove that heaven is wider than the raqia only if we accept the point at issue that the raqia must be solid; therefore, a non-solid heaven cannot be completely synonymous with the raqia. This is a clear example of assuming the point at issue…

        2. jlwile says:

          Excellent links, Steve. Thanks!

  4. […] "Since today is Columbus Day, I thought I would discuss a myth commonly associated with the man. I learned it in school, as did many others. It’s the myth that people in Columbus’s day thought the earth was flat."  […]

  5. Arick says:

    The Bible includes many verses that either imply or only support a flat earth concept:
    Daniel 4:10,
    Matthew 4:8,
    Luke 4:5,
    Isaiah 40:22,
    Isaiah 11:12,
    Revelations 7:1

    1. jlwile says:

      Arick, none of those verses imply or support a flat earth. As I explained to Benjamin above:

      Daniel 4:10 is about a dream. It does not even imply that such a thing actually exists in the natural world.

      Matthew 4:8 and Luke 4:5 describe an encounter between the Devil and Jesus. It is clearly dealing with supernatural things, not the natural world.

      Isaiah 11:12 and Revelations 7:1 use the term “four corners,” which I also explained to Benjamin above doesn’t imply a flat earth. It is a common phrase used still today to refer to the four cardinal directions, and people who use it are not referring to a flat earth. They are simply referring to the entire world. There is no reason to think it is being used any differently in Scripture.

      As for the other verse, Isaiah 40:22 actually implies a spherical earth. As the link I gave to Benjamin above says:

      Note, the Biblical Hebrew word for “circle” (חוג—chuwg) can also mean “round” or “sphere.”

      1. Aaron says:

        For me, Isaiah 40:22, and other passages that use the word ‘chuwg’ are really the only interesting passages that allow the OT writers the possibility that they thought the earth was a flat disk.

        Personally, I’m ok with that. The Bible isn’t a science textbook, and whether ‘chuwg’ means disk or oblate spheroid doesn’t really impact the functional or descriptive intent of the passage in question: God is powerful.

        In saying this, am I compromising on the inerrancy of scripture? As far as I can tell, no…

    2. steve hays says:

      The Book of Revelation is an extended vision, like an inspired dream.

  6. Carl says:

    Based on redundancy fo the responses you have received, Dr. Wile, I wonder if these verses are standard proof texts for people of a certain persuasion. Perhaps not, but the repetition appears mantra-like.

    In my Pre-Calculus class we always run across a problem with Eratosthnes calculating the circumference of the earth. I cannot help but use that to show to my students that myths abound regarding history and religion. I have found the following quotes and sources helpful:

    If we examine the work of even early- medieval writers, we find that with few exceptions they held a spherical- earth theory. Among the early church fathers, Augustine (354–430), Jerome (d. 420), and Ambrose (d. 420) all agreed that the earth was a sphere…. From the seventh century to the fourteenth, every important medieval thinker concerned about the natural world stated more or less explicitly that the world was a round globe, many of them incorporating Ptolemy’s astronomy and Aristotle’s physics into their work. Thomas Aquinas (d. 1274), for example, followed Aristotle’s proof in demonstrating that the changing positions of the constellations as one moved about on the earth’s surface indicated the spherical shape of the earth. Roger Bacon (d. 1294), in his Opus Maius(ca. 1270), stated that the world was round, that the southern antipodes were inhabited, and that the sun’s passage along the line of the ecliptic affected climates of different parts of the world. Albertus Magnus (d. 1280) agreed with Bacon’s findings, while Michael Scot (d. 1234) “compared the earth, surrounded by water, to the yolk of an egg and the spheres of the universe to the layers of an onion.” Perhaps the most influential were Jean de Sacrobosco, whose De Sphera (ca. 1230) demonstrated that the earth was a globe, and Pierre d’Ailly (1350–1410), archbishop of Cambrai, whose Imago Mundi(written in 1410) discussed the sphericity of the earth.8 Both of these books enjoyed great popularity; Sacrobosco’s book was used as a basic textbook throughout the Middle Ages, while d’Ailly’s book was read by early explorers like Columbus…. With the exception of Cosmas, no medieval writer denied that the earth was spherical—and the Catholic church never took a stand on the issue…. We must rely on reports written by Columbus’s son Fernando and by Bartolemé de las Casas, a Spanish priest who wrote a history of the New World. Both tell us that the learned men at Salamanca were aware of the current debates about the size of the earth, the likelihood of inhabitants in other parts of the world, and the possibility of sailing through the torrid zone at the equator. They challenged Columbus on his claim to having knowledge superior to that of the ancients and on his ability to do what he proposed. They did not, however, deny that the earth was spherical, but rather used its sphericity in their arguments against Columbus, arguing that the round earth was larger than Columbus claimed and that his circumnavigation would take too long to complete…. Those who want to preserve Columbus as an icon for the historic moment when the world became round might appeal to the common people. After all, weren’t Columbus’s sailors afraid of falling off the end of the earth? No, they weren’t. According to Columbus’s diary, the sailors had two specific complaints. First, they expressed concern that the voyage was taking longer than Columbus had promised. Second, they were frightened that, because the wind seemed to blow constantly due west, they would be unable to make the return voyage eastward (33, 34).
    –From Galileo Goes to Jail and Other Myths about Science and Religion. Ed by Ronald L. Numbers. “Myth 3: That the Medieval Christians Taught that the Earth Was Flat.” Leslie B. Cormack. 28-34. Harvard U. Press; 2009.

    Those who have written about the nature of the universe have discussed at length the shape of the earth. If it be spherical or cylindrical, if it resemble a disc and is equally rounded in all parts, or if it has the forth of a winnowing basket and is hollow in the middle; all these conjectures have been suggested by cosmographers, each one upsetting that of his predecessor. It will not lead me to give less importance to the creation of the universe, that the servant of God, Moses, is silent as to shapes; he has not said that the earth is a hundred and eighty thousand furlongs in circumference; he has not measured into what extent of air its shadow projects itself whilst the sun revolves around it, nor stated how this shadow, casting itself upon the moon, produces eclipses.
    –From Basil the Great (Hexaemeron, C. 350 AD).

    We must not suppose that the idea of the roundness of the earth was invented by Columbus. Although there were other theories about its shape, many intelligent men well understood that the
    earth was a globe, and that the Indies, though they were always reached from Europe by going to the East, must be on the west of Europe also. There is a very funny story in the travels of
    Mandeville, in which a traveler is represented as having gone, mostly on foot, through all the countries of Asia, but finally determines to return to Norway, his home. In his farthest eastern
    investigation, he hears some people calling their cattle by a peculiar cry, which he had never heard before. After he returned home, it was necessary for him to take a day’s journey westward
    to look after some cattle he had lost. Finding these cattle, he also heard the same cry of people calling cattle, which he had heard in the extreme East, and now learned, for the first time,
    that he had gone round the world on foot, to turn and come back by the same route, when he was only a day’s journey from home, Columbus was acquainted with such stories as this, and also had the astronomical knowledge which almost made him know that the world was round, “and, like a ball, goes spinning in the air.” The difficulty was to persuade other people that, because of this roundness, it would be possible to attain Asia by sailing to the West. Now all the geographers of repute supposed that there was not nearly so large a distance as there proved to be, in truth, between Europe and Asia. Thus, in the geography of Ptolemy, which was the standard book at that time, one hundred and thirty five degrees, a little more than one third of the earth’s circumference, is given to the space between the extreme eastern part of the Indies and the Canary Islands. In fact, as we now know, the distance is one hundred and eighty degrees, half the world’s circumference. Had Columbus believed there was any such immense distance, he would never have undertaken his voyage. Almost all the detailed knowledge of the Indies which the people of his time had, was given by the explorations of Marco Polo, a Venetian traveler of the thirteenth century, whose book had long been in the possession of European readers. It is a very entertaining book now, and may well be recommended to young people who like stories of adventure. Marco Polo had visited the court of the Great Khan of Tartary at Pekin, the prince who brought the Chinese Empire into very much the condition in which it now is. He had, also, given accounts of Japan or Cipango, which he had himself never visited. Columbus knew, therefore, that, well east of the Indies, was the island of Cipango, and he aimed at that island, because he supposed that that was the nearest point to Europe, as in fact it is.

      Thanks for those excellent quotes, Carl. As far as the repeated verses are concerned, I don’t know if they are part of some standard “proof text” mantra. However, they are almost certainly the result of someone not investigating the issue much.

    2. Jonathan Sarfati says:

      Venerable Bede (673–735):

      “We call the earth a globe, not as if the shape of a sphere were expressed in the diversity of plains and mountains, but because, if all things are included in the outline, the earth’s circumference will represent the figure of a perfect globe. … For truly it is an orb placed in the centre of the universe; in its width it is like a circle, and not circular like a shield but rather like a ball, and it extends from its centre with perfect roundness on all sides.” (On the Reckoning of Time (De temporum ratione))

      Thomas Aquinas (1225–1274), wrote in his greatest work Summa Theologica/Theologiae, the standard theology textbook for the high Middle Ages:

      “The physicist proves the earth to be round by one means, the astronomer by another: for the latter proves this by means of mathematics, e.g. by the shapes of eclipses, or something of the sort; while the former proves it by means of physics, e.g. by the movement of heavy bodies towards the centre, and so forth.” (Question 54: The distinction of habits, Article 2, Reply to objection 2).

      Yet as soon as the sun is at the horizon, the whole hemisphere is illuminated from end to end. … Secondly, as to place, for in one hemisphere there was light, in the other darkness.

      Thirdly, as to time; because there was light for one and darkness for another in the same hemisphere; and this is signified by the words, “He called the light day, and the darkness night.” (first Part, Question 67)

  7. steve hays says:

    To take another example, consider fishermen. Say they live in a coastal village. Suppose these are “primitive,” prescientific fishermen.

    Even so, don’t they pay attention to the weather before they set sail? Do they go fishing when the skies are full of dark lowering clouds? Or do they go fishing on a clear sunny day?

    If they thought the sky was a dam that kept water back, except when sluice-gates were opened, rain would be utterly unpredictable. It could rain at any moment, on a clear sunny day. If rain was thought to come from the sky rather than the clouds, then it both could and would rain on cloudless days. A downpour could occur literally out of the blue.

    But, of course, fishermen know from experience that that isn’t the case. Their life depends on it. It’s dangerous to venture miles into the open sea with stormclouds on the horizon, much less right overhead. It’s completely unrealistic to imagine that ancient people didn’t notice these things.

    1. Benjamin A. Tagle says:

      There is a difference between the ‘phenomenon’ of rain and the ‘explanation’ for the rain. As you point out, people can certainly observe that the appearance of a certain type of cloud presages rain and plan accordingly. This does not mean that they know where the rain comes from besides that it comes down from the sky through the clouds, just as a child can recognize the danger of fire without knowing the mechanics of combustion.

      Take a container of water and throw the water up into the air. Does it stay in the air? Of course not. Human experience tells us that water is heavier than air. Doesn’t rain fall down and not up? Remember that a scientifically naïve culture does not know about ‘water vapor’. They may observe that boiling water makes it look something like a cloud but then it disappears (turns into air. Remember the earth-water-fire-air theory?). So a cloud must be something that is lighter than air in order to remain up there, and the rain cannot be in the clouds because water is heavier than air and would drag the clouds down to earth.

      So how do we go about explaining where rain comes from? This is what we mean when we speak of ‘cosmogony’—an explanation for how and why things came to be. We know that the ocean looks blue and the sky looks blue too so maybe there is water up there somewhere that escapes somehow to come down as rain. (Remember that scientifically naïve peoples do not know about refraction and reflection and will take it for granted that water is blue.) But something’s got to be holding back that water otherwise it would be coming down all the time. That’s where the idea of a barrier came from, as an attempted explanation for water that comes down from the sky (sometimes torrentially) but that just can’t simply be floating up there.

      Egyptian cosmogony has the body of the goddess Nut as a barrier between the order of our world and the surrounding chaos. The Babylonians had Tiamat, the ancient embodiment of the primordial waters, whose body forms the vault of heaven. The ancient Hebrews did away with the ‘bodies’ (and gods) altogether and postulated a ‘firmament’ between the world and the waters above, through the actions of one God.

      The cosmogonies of more than a few cultures have the universe arising out of some chaotic watery domain. The Creator brings order to this chaos, producing our world as we know it. Some similarities run through Genesis. In Gen. 1:2, the spirit of God moves (or hovers) over the waters. What waters? Apparently it is this same primordial, universe-encompassing ocean that other ancient peoples envisioned. There is no world because God has yet to form it.

      In verses 6-7, God makes a firmament to divide “the waters from the waters,” the waters below the firmament from the waters above the firmament. The firmament is in the midst of these waters.

      In verses 9-10, God makes dry land beneath the firmament but there are still waters above the firmament and the surrounding universe.

      Think about turning a cup over onto a plate and sinking the whole thing into a bathtub full of water. There is air inside the overturned cup which keeps the area on the plate (beneath the cup) dry. The cup (firmament) keeps the area ‘safe’ from the surrounding waters.

      This was a widespread (though not necessarily universal) belief in the ancient Near East. And it was logically consistent within their experience. Ancient peoples were not stupid–they just didn’t have the storehouse of accumulated science which we take for granted and which colors our viewpoints. They used the knowledge available to them to come up with a consistent explanatory framework (a theory) to make sense of their world.

        But as the article I have already linked to you clearly demonstrates, Benjamin, trying to force that belief into Genesis “…is based on a faulty analysis of the Hebrew linguistics.” It might have been a popular belief at the time (although the article by Noel K. Weeks I mentioned previously calls that into question), but it is not consistent with Genesis.

        “There is a difference between the ‘phenomenon’ of rain and the ‘explanation’ for the rain. As you point out, people can certainly observe that the appearance of a certain type of cloud presages rain and plan accordingly. This does not mean that they know where the rain comes from besides that it comes down from the sky through the clouds, just as a child can recognize the danger of fire without knowing the mechanics of combustion.”


        Did ancient people never notice that it only rains on cloudy days? Never when the sky is clear? Did they never make the connection?

And it’s more than inference. There are times when you can see rainclouds on the horizon. Above the clouds, the sky is bright and clear. You can actually see rain coming from the clouds. It’s not coming from the sky through the clouds. The clouds are emitting the rain.

        The sky above the clouds is clear. The sky below the clouds is dark, due to rain. You can see the sheets of rain at a distance, from an eye-level viewpoint. They obscure the sky behind the clouds and under the clouds, until the clouds dissipate.
        There’s no rain between the sky and the clouds. Only rain beneath the clouds. 

Likewise, you can be outside as rainclouds approach. At first it’s clear and dry overhead. When, however, the clouds are overhead, it begins to rain.

        Do you really think ancient people were so clueless that they never made these elementary connections?

        A lot of modern people are simply unobservant because they don’t live in the wild. Even if they go for a nature walk, they are glued to the display on their smartphones.

        “Egyptian cosmogony has the body of the goddess Nut as a barrier between the order of our world and the surrounding chaos. The Babylonians had Tiamat, the ancient embodiment of the primordial waters, whose body forms the vault of heaven.”
        And when “scientifically naive” people looked up at the sky, did they see the body of a naked woman overhead? Why does it not occur to you that that depiction is intentionally anthropomorphic?

        “In Gen. 1:2, the spirit of God moves (or hovers) over the waters. What waters? Apparently it is this same primordial, universe-encompassing ocean that other ancient peoples envisioned. There is no world because God has yet to form it.”

        The creation of the world begins in v1, not v2.

        “And it was logically consistent within their experience. Ancient peoples were not stupid–they just didn’t have the storehouse of accumulated science which we take for granted and which colors our viewpoints.”

        My arguments aren’t based on modern scientific knowledge, but on what any attentive, prescientific observer would be in a position to experience or notice.

    A few final thoughts on this topic, Dr. Wile, and thank you for your patience. I trust you are not saying that the ancient writers had hydrothermal vents in mind when they penned the phrase “fountains of the deep.” I think it is more likely that they were informed by their own worldview, namely that of a flat expanse of land surrounded by mountains which held up a solid firmament. The Hebrew word for the firmament is raqia’ which translates as something that is ‘spread out’ or ‘beaten out’ as in shaping metal. Here is a well-cited article which explores this topic. See []. The firmament was imagined as a solid, metallic bowl that maintained a dry earth under the surrounding expanse of water. See HarperCollins Bible Dictionary entry: [] and also the Anchor Bible Dictionary entry “Cosmogony, Cosmology”. Bear in mind that this is not ‘my’ lowly opinion, but that of the scholars who have studied the context within which the Bible was written.

    1. jlwile says:

      Benjamin, I am not saying anything about what the ancient writers had in mind, because there is no way to know that. I am just discussing what the Bible teaches, and it teaches nothing about a flat earth, a flat expanse of land surrounded by mountains which held up a solid firmament, etc. The “fountains of the deep” could easily refer to hydrothermal vents. It could also refer to some other fountains in the ocean.

      I would suggest this well-cited article, which indicates the firmament doesn’t refer to anything solid. Indeed, as the article indicates, one of the most important commentaries ever written on the first five books of Scripture defines firmament as “to stretch, to spread out, then beat or tread out…the spreading out of air, which surrounds the earth as an atmosphere.” As the article clearly shows, the Bible uses the term to refer to the atmosphere, not some odd, solid dome.

      Here is another well-cited article that concludes:

      We have set out the linguistics of rāqîa and argued that it means ‘expanse’. The expanse is whatever God did with the sky to separate the waters. ‘Expanse’ is a common choice for translators and commentators. The alternative of ‘dome/vault’ and the insistence that the rāqîa is solid is based on a faulty analysis of the Hebrew linguistics. [emphasis mine]

      As these two articles (and many others) clearly demonstrate, the fact that the firmament as mentioned in the Bible is not some odd, solid dome isn’t ‘my’ lowly opinion, but that of the scholars who have studied the original language and understand it better than you or me.

      1. Keith says:

        Thank you DR.Wile for this excellent information.
        I’m wondering if this recent discovery might explain the fountains of the deep?

        1. jlwile says:

          I am not sure that it does, Keith. The water is locked up in a mineral called ringwoodite. I am not sure how it could be released quickly enough to produce the effects of the “fountains of the deep.” Of course, there is a lot of stuff we don’t understand about what’s going on in the mantle, so I could easily be wrong.

      Unfortunately, atheists and their allies in BioLogos basically think that ancient people were stupid.
