Let me offer a slightly different view. First of all the Bible was not written by God. It was written by man. Specifically Roman monks translating it from Aramaic and Hebrew text. Secondly, Evolution is never touted by evolutionists as fact.
Evolution is a theory that was derived from facts.
Each new discovery adds or subtracts from the Theory of Evolution. The Bible is not based on any facts at all. Thirdly, I am not an atheist. I am a Christian. I believe that the Theory of Evolution is the best explanation of how things, living things that is, came to be.
