Discovering Design with Earth Science is Finally Available!

Because of difficulties surrounding supply chains, employment, etc., it took a lot longer than expected, but Discovering Design with Earth Science is finally here! I have to take a moment to praise my publisher, who truly went above and beyond what most publishers would do in this situation. The facility that usually does the printing told my publisher that they couldn’t get the books done in time to get them out to those who are starting school in August. As a result, my publisher ended up contacting several printers and found one that would do a “short run” (printing a smaller number of books) to meet the needs of those who were counting on the book being available in August. Short runs cost more money per book, so my publisher is sacrificing income in order to make the books available to those who need them. Not many publishers would do that, and I want to commend Berean Builders for its commitment to customer service!

The course covers earth science at the late junior high/early high school level. In practical terms, it could be used for either 8th or 9th grade, depending on the student. It covers the basic structure of the earth, geology, fossils, physical oceanography, weather, and space. Like all my courses, it has laboratory exercises built right into the book. Some of the exercises use household items, but there are several that require a kit which has a digital mass scale, some chemistry supplies, and specific samples of sediments, rocks, minerals, and fossils.

As I have tried to do in the past, I strive to present both sides when it comes to the age of the earth. Throughout the first nine chapters of the book, students will learn the data that lead many scientists to conclude that the earth is billions of years old, but they will also learn the data that lead some scientists to believe the earth is thousands of years old. I do not tell the students what I believe, but they can probably figure it out if they want to. Nevertheless, here is how I end the ninth chapter:

“Before I end this chapter, however, I need to make you aware of one very important fact. As a knowledgeable scientist, I could have focused on just the evidence favoring uniformitarianism and against the YEC (young-earth creationist) view. As a result, I could have easily convinced you that science clearly demonstrates that the earth is billions of years old and the uniformitarian view of the geosphere is correct. I could also have focused on the evidence for catastrophism and against uniformitarianism, and I could have easily convinced you that science clearly demonstrates the earth is only thousands of years old, and the YEC view of the geosphere is correct.

Unfortunately, this is something every student experiences. Because your teachers and the authors of your textbooks know a lot more than you do, they can easily convince you of pretty much anything they want. Being a good scientist requires that you respectfully read and listen, but also investigate the issue for yourself. This is probably the most important thing to learn from this chapter. In fact, it is probably the most important thing to learn from all your education:

Regardless of how convincing teachers or textbooks are, do not form an opinion until you have looked at all sides of an issue. Otherwise, you might end up being fooled.”

The American Biology Teacher Uses False Statements to Reassure Teachers

When dinosaur fossils like this one are tested, they contain carbon-14 in significant quantities, which is not possible if they are millions of years old.
Quite some time ago, a reader sent me this article from The American Biology Teacher. It attempts to assure biology teachers that the large amounts of carbon-14 found in dinosaur fossils is compatible with the scientifically-irresponsible idea that those fossils are millions of years old. The reader asked me to comment on the article, since I have said several times that carbon-14 in dinosaur bones is a very strong indication that the bones are not millions of years old. The author of this article (Dr. Philip J. Senter), however, is confident that this is not a problem at all. How can he be so confident? Because he seems to believe a lot of false information.

Early on, he makes a statement that indicates he has not studied carbon-14 dating very seriously:

…bone mineral is usually useless for radiocarbon dating, even though the carbonate that bone mineral incorporates during life contains 14C. The uselessness of bone mineral for radiocarbon dating is due to the fact that bone mineral accumulates new 14C after death, yielding a falsely young radiocarbon “age.”

This statement is utterly false, and anyone who knows carbon-14 dating would know that. Hundreds of radiocarbon dates have been published in the scientific literature using bioapatite, a bone mineral. This study examined using bioapatite in carbon-14 dating extensively, comparing it to two other commonly-used substances in carbon-14 dating. It concluded:

Most Holocene samples exhibit reliable 14C ages on the bioapatite fraction. Late Pleistocene samples have shown reliable results even for extremely poorly preserved bone in the case of samples derived from a non-carbonate environment.

The Holocene supposedly dates back to about 11,700 years, while the Pleistocene supposedly goes back to 2.6 million years. “Late Pleistocene” samples, then, would be samples that go back to the limits of carbon-14 dating (about 50,000 years old). Indeed, in that study, one of the samples had a carbon-14 date of 37,000 years old, which is older than most of the dinosaur bones that have been dated with carbon-14. So the idea that minerals from bone are “useless” for carbon-14 dating is demonstrably false.

Dr. Senter tries to back up his statement with a reference, but the reference doesn’t invalidate the use of bioapatite in carbon-14 dating at all. It does indicate that when you compare the date derived from collagen (a non-mineral that is often used in carbon-14 dating) to the date derived from bioapatite, the bioapatite date is often younger. However, the results depend heavily on where the fossil was found. More importantly, we know this has nothing to do with the carbon-14 dates of dinosaur bones, since many dinosaur fossils have been dated using both mineral and non-mineral samples (including collagen), and the ages are similar. In a hadrosaur fossil, for example, bioapatite dated as 25,670 years old, while the collagen dated as 23,170 years old. Note that contrary to the study Senter cites, in this case, the bioapatite age is older than the collagen age.

Senter then tries to explain why dinosaur bones read so young with carbon-14 dating. Most of his argument boil down to the idea that modern carbon has gotten into the fossils, and since the modern carbon is very young, it makes the fossil read young. The problem with that, of course, is that if modern carbon is getting into the fossil from the environment, there must be more contamination near the surface of the fossil and less near the center of the fossil. Thus, the carbon-14 age of the bone should vary depending on where in the bone the sample was taken. However, that’s not what is seen. In this study, Figure 7 has circles around the dates for samples taken from different parts of the same bone. They show very good agreement, indicating that what is being detected is not from contamination.

There is one argument Dr. Senter makes which isn’t about contamination. He says that radioactive materials can be absorbed by a bone, and those radioactive materials can cause nuclear reactions which will add carbon-14 to the bone, making it look young. Once again, he cites studies to support his claim, such as this one, but once again, the studies don’t support his claim. For example, the study I just linked shows how uranium decay can lead to the production of carbon-14, but as anyone who understands nuclear reactions would tell you, the effect is ridiculously small. Indeed, the study shows that nuclear reactions can account for no more than one hundreth (1/100) of the lowest amount of carbon-14 detected in dinosaur bones! Thus, there is no way that nuclear reactions are a viable means of explaining around the carbon-14 found in dinosaur bones.

In the end, then, we see that Dr. Senter must use false information to assure his readers that carbon-14 in dinosaur bones doesn’t invalidate the dogma that they are millions of years old. Unfortunately, since many teachers read the magazine in which his article was published, I am sure that this false information will be spread around, fooling unsuspecting students. Nevertheless, the more this is investigated, the more we will see that it poses a huge problem for those who are committed to believing that dinosaurs lived millions of years ago.

Another Dinosaur Soft Tissue Discovery by Mark Armitage

In several previous articles (here, here, here, here, and here), I have been highlighting the groundbreaking work of Mark Armitage at the Dinosaur Soft Tissue Research Institute (DSTRI). If you haven’t heard about the amazing work he has been doing, you should read every link given above. If you have been following Armitage’s cutting-edge original research, then you will be pleased to learn that he has published yet another article with yet another first in the field of paleontology.

The article is entitled, “First Report of Peripheral Nerves in Bone from Triceratops horridus Occipital Condyle,” and even if you get lost in the terminology, the pictures are well worth perusing. Essentially, Armitage does a microscopic analysis of nerves from a chicken (like the one pictured on the left above) and compares them to nerves that were isolated from the condyle (the rounded end of a horn) of a Triceratops fossil (like the one pictured in the right above). He shows that the structures from the fossil have all the physical characteristics of the chicken nerves, which indicates that they really are nerves from a vertebrate animal. That means they are not contaminants. They came from the dinosaur.

Look, for example, at the pictures above. The white bars tell you the scale in micrometers (millionths of a meter). Notice the pattern of dark lines wrapping around the chicken nerve on the left. That is characteristic of a sheath that wraps around the bundle of fibers which makes up the nerve. As you can see, the same pattern appears in the structure that was isolated from the Triceratops fossil, which is shown on the right. Two even more stunning photographs appear on page 5 of the article. In Figures 12 and 13, you can actually see deatils of the sheaths themselves. They are extremely thin and delicate, and yet they were found in a bone that is supposed to be 65 million years old!

It is important to note that these aren’t stiff, petrified structures. Armitage removed the minerals that had preserved the bone (he “decalcified” it), leaving soft tissues behind. As he says in the article:

The flexibility of individual decalcified nerves was astonishing. Nerves held at each end with fine needle forceps only broke into two pieces after repeated tugging. An example of the flexibility of these nerves is seen in Figure 15 where the fascicle rotates through a gentle, unbroken loop and descends into other curvatures before terminating to a point.

Those who are forced by their preconceptions to believe that dinosaur fossils are millions of years old are still scrambling to find any way in which delicate, soft tissues can avoid decomposition for millions of years. The original discoverer of soft tissue in dinosaur bones, Dr. Mary Schweitzer, published an attempted explanation a while ago, but Armitage himself has shown that it isn’t consistent with the data. Chemists have also shown that the explanation isn’t consistent with what we know about chemistry.

Those who are forced to believe in an ancient earth will, no doubt, come up with more special pleading to try to explain how soft tissue can avoid decomposition for millions of years. But for those who are willing to actually follow the data, it is clear that the most reasonable explanation is that the bones are not millions of years old.

Microscopic Analysis of Dinosaur Soft Tissue Casts More Doubt on Proposed Preservation Mechanism

The dark mass near the center is the cell body of a dinosaur bone cell. The various “arms” extending from the body are its filipodial extensions. (click for credit)
I have written a lot about soft tissue found in dinosaur fossils and other fossils that are supposed to be millions of years old (see here, here, here, here, here, and here, for example). Right now, the best work being done on this issue comes from the Dinosaur Soft Tissue Research Institute, which is run by microscopist and young-earth creationist Mark Armitage. Without the help of government grants, he and his colleagues have produced some truly incredible work. Their latest contribution was published in Microscopy Today, and it strengthens the case that these fossils cannot be millions of years old. As always, I encourage you to read the article in its entirety, but here is my “color commentary.”

First, the article shows more incredible, delicate structures that would not be expected to survive any preservation process that would protect them for millions of years. For the first time in the scientific literature, there are two excellent pictures of dinosaur vein valves (Figures 2 and 3), features that are so delicate they are hard to extract from animals that have just recently died. In another first, he shows a nerve from the same fossil (Figure 6). In that nerve, you can see the delicate Bands of Fontana, structures that are unique to nerves.

He also shows a bone cell from the same fossil (Figure 7). While bone cells from dinosaur fossils have been published in the scientific literature, this particular one is very important. Bone cells have characteristic structures called filipodial extensions that are remarkably thin (widths of less than 200 billionths of a meter). The bone cell shown in their study has a filipodial extension that is 24 millionths of a meter long. That doesn’t sound like much, but it is about 30% longer than any other dinosaur filipodial extension found in the literature. This is important, because its length is more than 100 times its width. Think about a structure with those dimensions made out of soft tissue. It would be ridiculously fragile, yet there it is in a dinosaur fossil!

Second, and more importantly, he shows that the current explanation evolutionists have for the preservation of soft tissue in dinosaur fossils doesn’t work. Dr. Mary Schweitzer was the first to give strong evidence for the existence of soft tissue in dinosaur fossils, but she is committed to an evolutionary view. As a result, she needs to find an explanation for how such tissue could survive for millions of years. Seven years ago, she published a study in which she hoped to show that iron from the blood of a dinosaur could produce certain reactions that would preserve the tissues. I wrote about her explanation at the time and how it didn’t seem to make sense based on what we knew. Later on, better chemists than I wrote a detailed analysis about how her explanation is inconsistent with the data.

This new paper demonstrates rather conclusively that Schweitzer’s explanation doesn’t work for the fossil being discussed. Armitage and his colleague (Jim Solliday) search the filipodial extensions of bone cells that are found right outside a canal that held a blood vessel. Since the cells are so close to what was a blood vessel, and since the filipodial extensions are so delicate, those iron-induced reactions should produce noticeable effects on the filipodial extensions. He shows that those effects are not present. Thus, it is unlikely that such reactions happened at all in the fossil.

Also, in her study, Schweitzer took great pains to prevent blood clotting so that iron from the blood could be distributed throughout the soft tissue she was trying to preserve. However, Armitage and Solliday present strong evidence for massive blood clotting in their fossil. This would prevent iron from being able to promote any tissue-preserving reactions. While their evidence is strong, however, it is not conclusive. Thus, as they suggest, more research needs to be done.

The Dinosaur Soft Tissue Research Institute is on the forefront of this issue in science, and they are doing it without the massive government grants available to organizations who are desperately trying to fit the data into an evolutionary framework. If you have the means, I suggest that you make a donation to keep science progressing in this area.

Did This Bird Go Extinct and Re-Evolve? I Doubt It.

A flightless Railbird on the Aldabra atoll in the Indian Ocean (click for credit)

Over the past few days, several people have sent me articles like this one, which makes a rather fantastic claim:

The Aldabra white-throated rail bird was declared extinct, a victim of rising sea levels almost 100,000 years ago.

However, the flightless brown bird has recently been spotted – leaving scientists scratching their heads as to how – and why – the species has come back to life.

What do you conclude from reading that? The article seems to be saying that no one had ever seen this bird before; it was only known from the fossil record. Now, however, living versions of it have been seen, and how they came back from extinction is a mystery. Unfortunately, like many “science news” stories, this one distorts the science to the point that it is deceptive and misleading.

The science that is being distorted comes from a study published last year. A responsible article that describes the study can be found here. While the study and the responsible article don’t distort the science, I do think the conclusion that they draw is not the only one consistent with the data.

Let’s start with the bird that is being discussed. It’s the Aldabra white-throated rail, whose scientific name is Dryolimnas [cuvieri] aldabranus. It lives on the Aldabra atoll in the Indian Ocean and is nearly identical to white-throated rails (Dryolimnas cuvieri) found in other parts of the world, like Madagascar. However, the ones on the Aldabra atoll cannot fly, while the others can. As a result, the flightless birds on the atoll are considered a subspecies of the version that can fly.

While we cannot say for sure, the generally-accepted origin story for the Aldabra white-throated rail is that normal white-throated rails landed on the atoll, and since there were no predators there, they stayed. Since they didn’t need to fly anymore, they evolved into flightless birds over several generations. This makes sense, because when a population of organisms doesn’t need a particular biological trait, mutations can degrade those traits without affecting survivability. In addition, DNA is so incredibly well-designed that over the course of generations, it can “turn off” genes that are no longer used in order to save energy. As a result, it makes sense that these flightless birds are descendants from birds that could originally fly.

Why do these articles discuss the birds being extinct at one point? Because the authors of the scientific study looked at the fossil record of the atoll. Using scientifically-irresponisble dating methods, they came to the conclusion that the atoll was completely underwater about 140,000 years ago. When they looked at fossils they interpreted to be older than 140,000 years, they found two bones that seem identical to the corresponding bones in the Aldabra white-throated rails that currently live on the atoll. Thus, they conclude that these flightless birds lived on the atoll before it went completely underwater.

Well, since the birds couldn’t fly, the authors assume that they all died when the atoll was underwater. However, in fossils that they interpret as being deposited after ocean levels decreased and the atoll was no longer underwater, they found another bone that looks similar to the corresponding bones in white-throated rails that can fly. However, it is heavier and more robust than what is found in those birds, but still lighter than what is found in the flightless Aldabra white-throated rails. In other words, it seems to be “in between” the bone of a normal white-throated rail and a flightless white-throated rail. To them, that gives “irrefutable evidence” (their words) that the Aldabra white-throated rails evolved twice: once before the atoll went underwater, and once after.

While their interpretation of the evidence makes sense and is consistent with all the known data, their case is certainly not “irrefutable.” First, you have to assume that they are interpreting the fossil record correctly. There is a lot of evidence to indicate the earth isn’t anywhere close to 140,000 years old, and if that evidence is correct, then their entire explanation is wrong. Also, even if the earth is as old as these scientists want to believe, the authors’ explanation is not the only one consistent with the data. We know that flightless animals can move from place to place on floating mats of vegetation. This is called “rafting,” and it is used by both evolutionists and creationists to explain the worldwide distribution of certain animals. If the atoll flooded like the authors think, the flightless birds could have survived by rafting. What about that one bone that is “in between” the two subspecies? There are natural variations in all bones. A “more robust” bone from a normal white-throated rail can be explained by natural variation within a population of normal white-throated rails.

The main reason I am writing about this is not to argue with the authors. It’s to point out the deceptiveness of articles like the one I quoted at the beginning of the post. As I have said many times before, do not believe the things you read in the popular press when it comes to science. Most “science journalists” are profoundly ill-equipped to understand science, and usually quite poor journalists as well.

No Other Explanation: Dinosaur DNA!

(image from paper being discussed)

Despite the overwhelming evidence, there are some who are skeptical that soft tissue can be found in dinosaur fossils. Even among those who think that there may be soft tissue in some dinosaur fossils, there are those who think that there is no way complex molecules like DNA could possibly be found in that tissue. Well, Dr. Mary Schweitzer and her colleagues have recently published a study that, as far as I am concerned, should put all doubts to rest. Yes, dinosaur fossils do contain soft tissue and original dinosaur biomolecules, including DNA.

The study involves a detailed investigation of fossils from duck-billed dinosaur (Hypacrosaurus stebingeri) nestlings that are supposed to be 75 million years old. The authors examined cartilage tissue under the microscope and found what were obviously cells. Of course, that’s nothing unusual. The Dinosaur Soft Tissue Research Institute has some really great examples of dinosaur cells and other delicate structures from dinosaur fossils. They also have evidence for RNA in the fossils (see here, here, and here).

What’s new (and in my mind definitive) about this study is that they applied two different DNA stains to the tissue. The stains are designed to bind only to DNA, and when you use two different stains and see them both bind to the same structures, you have doubly confirmed the presence of DNA. Of course, what they saw could be DNA stains binding to DNA that contaminated the fossil, right? Wrong! The image at the top of the post indicates why. If I ask anyone who has taken a good high school biology class what the red box is drawn around, he or she should be able to tell me.

More Incredible Dinosaur Soft Tissue Results

An axon from a nerve fiber, found in a triceratops fossil. (image taken from the video discussed below)

The Dinosaur Soft Tissue Research Institute is producing some incredible results. About two months ago, I discussed a video in which the institute’s founder, Mark Armitage, showed some of them. Recently, Armitage posted another video that shows even more results, and once again, they are amazing.

If you don’t have time to watch the entire video, let me summarize what I consider to be the two most amazing things shown. In my previous post, I told you that Armitage shows delicate vein valves that he extracted from soft tissue found in a triceratops fossil. It is amazing that he could get them, since they are so delicate that I end up destroying them when I try to get them from a dissection. More importantly, there is no possible way that such a vein valve could be from any source other than the dinosaur, since no organism that could possibly contaminate the fossil produces such structures. Thus, these vein valves are clearly original tissue from the dinosaur itself.

At 2:49 in this video, he shows not only the vein valve, but he shows that the wispy tissue which covers the valve when it is close is still 100% intact! How does he do that? He traps bacteria underneath the closed valve. The tissue is so thin that you can actually see the bacteria swimming around underneath it, trying to get out! The bacteria are obviously the result of contamination, but there is simply no way that the vein valve can be explained that way. So the video shows incredibly delicate dinosaur tissue (so delicate that you can see through it) that is still soft! That’s strong evidence that the fossil is not millions of years old!

Incredibly Fragile Dinosaur Soft Tissue

Two images of the delicate, one-way valves from veins. They were found in dinosaur soft tissue!
(Image copied from the presentation embedded below)

Mark Armitage and James Solliday at the Dinosaur Soft Tissue Research Institute have been doing some amazing work. On October 5th, Mr. Armitage presented their findings at Lower Columbia College. Apparently, he has not yet received the video of that presentation, so he kindly posted a quick overview of the content. To me, it is astounding:

While everyone should watch all 15 minutes of the presentation, I want to highlight the things that I think are most important.

At 2:29, he shows two images that elicited an audible gasp from me when I first saw them. To understand just how incredible the images are, you need to know that there are one-way valves found in vertebrate veins. This is because the blood pressure in a vein is so low that blood can actually travel backwards. To prevent that, there are delicate, one-way valves throughout the veins. They open when the blood is flowing the correct way, and they close to prevent it flowing backwards. In the left-hand part of the image at the top of the post (copied from the presentation), you see a circle with what looks like a partially-opened tent flap. The circle is the base of the valve, and the “tent flap” is the delicate membrane that opens and closes. In that image, the valve is partly open. On the right-hand side, the valve is fully open.

This is incredible to me, because I have tried to dissect animals and extract these valves. I have never been able to. They are so delicate that I end up destroying them in the dissection process. Now, of course, I am not much of a biologist, and I am even less of an expert at dissection. Nevertheless, my experience with them indicates that they are absurdly delicate. Yet, here they are in a dinosaur fossil! Not only does this give evidence that the fossil is not millions of years old, but it also shows that these are definitely not structures that come from fungi or bacteria which recently invaded the fossil. Bacteria and fungi do not build structures with these delicate, one-way valves! He also presents other evidence that rules out bacterial and fungal contamination.

At 8:22, he shows red blood cells from a fossil that is supposed to be 400 million years old! The cells have the appropriate size and shape for red blood cells. Later on (12:05), he shows a blood vessel from a dinosaur fossil that has not even collapsed! It has an air bubble in it. When he does a stain test to see what is in the blood vessel, the test indicates that there is RNA in the blood vessel!

At 6:47, he shows what appears to be blood clotted in the tissue. He shows how it behaves just like you would expect blood to behave when exposed to polarized light, and he also shows that iron from the blood has not spread into the bone tissue. This is important, because Dr. Mary Schweitzer has proposed that iron might be preserving the soft tissue found in dinosaur bones. There has already been several arguments (see here and here) that seem to invalidate Dr. Schweitzer’s hypothesis, but this observation is the nail in the coffin. Iron can’t be preserving bone tissue if it doesn’t spread into the bone to begin with!

I have said this before and will say it again: It’s a wonderful time to be a young-earth creationist!

Cool Video of a Soft Dinosaur Cell

A dinosaur fossil (left) and a cell that came from a different part of the same fossil assemblage (right)
(Images copyright Mark Armitage. Click for source)

A couple of years ago, I wrote about the remarkable dinosaur research being done by microscopist Mark Armitage. The story discussed two scientific articles he wrote about finding soft dinosaur cells in a Triceratops fossil. Well, Armitage is continuing his research at the Dinosaur Soft Tissue Research Institute in the state of Washington. The pictures above represent some new results: soft bone cells from a Nanotyrannus fossil.

Now whether or not there is such a thing as a Nanotyrannus is actually a matter of debate. Some paleontologists think the fossils are really from a juvenile Tyrannosaurus. So it might be a different species, or it might just be a juvenile form of an already-known species. Regardless of which is correct, it is well accepted that these fossils have been found in Cretaceous rock that is supposed to be about 65 million years old. It’s hard to understand how any cellular material could have survived for that long without being fossilized. Nevertheless, the cells that Armitage has extracted from the fossil are soft, as shown in the video below.

Of course, it is always possible that the cell is not really from the dinosaur. However, that’s a bit hard to believe. It came from a bone, and it has all the visual characteristics of an osteocyte, which is a bone cell. I can’t think of any possible contaminant that has the size, shape, and filipodial extensions that you see in the video. Also, remember that Armitage previously extracted soft bone cells from a Triceratops fossil. Thus, if this is a contaminant, it must be common to two completely separate fossils (or somehow introduced by Armitage’s process, which once again, is hard to believe).

I think it is reasonable to conclude that Armitage is, indeed, isolating soft dinosaur bone cells. He plans to make a presentation at Lower Columbia College in Longview Washington, on October 5th 2019, at 7 pm. In that presentation, it looks like he will also discuss how the soft tissues from which his cells are isolated react to stains for DNA and RNA. I won’t be able to make it, but I sincerely hope that it is recorded and that Armitage eventually writes another article about his continuing research!

How I Address the Age of the Earth in My Courses

My publisher has been getting several questions about how I address the age of the earth in my science courses. This probably stems from the fact that there is a lot of misinformation going through the homeschooling community regarding my position on the issue. I thought I would try to clear things up with a post.

First, my position on the age of the earth hasn’t changed in more than thirty years. I turned from atheism to Christianity in my late high school years, and at that time, I was happy to believe what my teachers told me about the age of the earth. It was more than four billion years old. I was told that we knew this because of radiometric dating methods, which involved studying the relative amounts of radioactive atoms in rocks and fossils. This “fact” of science was later reinforced when I went to university, so I was still happy to believe it.

Then I started my Ph.D. program in nuclear chemistry. I learned about radioactive decay in detail and started doing experiments with nuclear reactions. Most of my work was done at the University of Rochester Nuclear Structure Research Lab, which also had a group that did radiometric dating. I never did any of that work myself, but I watched them do their experiments, asked them questions, listened to their presentations at the lab, etc. Based on what I learned there, I decided that I couldn’t put much faith in the ages given by radiometric dating.

This caused me to question the age of the earth from a scientific perspective. Theologically, I wasn’t committed to any age for the earth. Certainly the most straightforward interpretation of Genesis is that the universe and all it contains was created in six solar days, and that leads to a young-earth view. At the same time, however, there were early church Fathers (as well as ancient Jewish theologians) who didn’t interpret the days in Genesis that way. So I attempted to investigate the subject with an open mind. I found that in my view, science makes a lot more sense if the earth is thousands of years old rather than billions of years old, so I started believing in a young earth. The more I have studied science, the more convinced I have become that the earth is only thousands of years old.
