Of course, this isn't evidence against theism (I think), but it makes me think that religious apologetics is flawed and should be abandoned.
I don’t know about your history, but I was brought up in environment, where most of the people I grew up were Christians, and for some times I was considering joining one of the churches, since I was 15, after my sister gave me my first Bible.
So I am quite familiar with the Bible, more so than with other religions and other scriptures. So for some times I was believer.
And during those times, when I did believe, I didn’t try to mix or didn’t try to compare religion with sciences.
Although, I was aware of dinosaurs and the Neanderthals, and I have heard of mutations (mostly from movies and tv series), I was never a biology student during high school and college days, and in biology I didn't go beyond Year 9 high school science. And when I went to study civil engineering in college during the mid-80s, I was more focused in applied physics, applied maths and tiny bit of chemistry that were essential for civil engineering.
My points in sharing history with you, I didn’t know anything about Charles Darwin, Evolution or Natural Selection, or anything else. And though I did hear of “survival of the fittest”, I seriously didn’t know what it mean. And though my high school science did include genetics, Evolution never came up, because it was just very basic genetics.
My points, my knowledge in biology was seriously limited, from 1981 (when I first became interested in the Bible) to 2003 (when I first joined a Internet forum). In fact, although I did know about creation from Genesis, I also never heard of Creationism, and didn’t know there were groups of people called “creationists”. I didn’t know there were argument between Creationism and Evolution.
Back then, before joining a forum, I didn’t know much about astronomy, astrophysics and modern cosmology, and I have never heard of the Big Bang. Although I was interested in hearing news of space missions, or seeing new images from the Hubble, i never took the times to actually learn about them.
But everything changed when I joined a forum in early 2003. I had joined forum for computer programmers and IT, because in 1999 I graduated in computer science (change in career, I started the course in 1995), the same year I created my website called Timeless Myths (in 1999).
Anyway this forum, has a section on Religion, and I noticed that members were arguing back and forth, about Evolution and Creationism. And I was clueless as to why the two sides were so fierce in their arguments.
Like I said I already knew about Genesis creation and flood, but I wasn’t aware about Creationism, but I was pretty much in the dark about evolutionary biology, so later during the year (2003), I borrowed my cousin’s old biology textbook, and read some chapters about evolution, particularly Natural Selection.
The more I learned, the more I felt that science were right about Evolution, and I began questioning Genesis.
I actually became more interested in physics and astronomy, and over the years that followed, I started reading areas in physics that I never learn in high school and colleges, like Particle Physics, Quantum Mechanics, Relativity, Nuclear Physics, as well as about the Big Bang.
Now, I am no biologist, nor am I qualified experts in physics and cosmology, but I have learned enough to know that creationists are wrong about so many things.
Plus, this is a public forums, not Peer Review organisation, but there are some members here, who are qualified in their respective fields in science, and they certainly know far more than me.
Anyway, I think that some theists, especially Young Earth creationists, are their own worse enemies, because they have put their respective religions and their bible under scrutiny, by trying to promote their beliefs in Genesis as “science”, with propaganda and misinformation not about sciences, but with their belief and their theism.
BTW, I have being agnostic since 2000, not because of Evolution vs Creationism, but because I began to question the Christian Messianic prophecies, starting with Matthew 1:22-23 in comparison with the original sign - Isaiah 7:14-17. My change in belief had nothing to do with Evolution or the Big Bang cosmology...but the creationist stance didn’t help their cause.
