Isn't it possible that the religious bent of these scientists is the RESULT of scientific discovery?
Maybe, but it never has been.
Every creationist who used to be a scientist became a Christian first, and then was convinced that the Bible had to be literally true if their faith was to have validity.
In other words, what you claim has never been the case - the "evidence" for creationism has never convinced anyone but those who had already decided they had to believe it.
You're free to try to prove me wrong, though. Find a bio where it was the evidence and not the dogma that convinced a biologist.
