Bill,
Belief in Jesus Christ as your personal savior does not in any way preclude an acceptance of the evidence for the evolutionary process.
Note the difference:
The divinity of Jesus can neither be proven or disproven. One accepts it on faith alone.
The process of evolution is based on the evidence of similarity of structures in both past and present life forms, comparative anatomy of present-day species, and more subtle evidence like protein homology (with a tip o’ the hat to Ben). The evidence for evolution in no way depends on faith.
I am an atheist because I take nothing on faith. I see absolutely no evidence anywhere for the existence of supernatural phenomena.
Another reason why I became an atheist was because of the conduct of Christians. My experience with Christians showed that while there was an enlightened minority, the majority of the Christians I met were uneducated and bigoted. I met a lot of mean Christians who hated Catholics, blacks, and Jews. When I was a boy Scout, the Christian church where my troop met wouldn’t allow me to bring a friend of mine who was black. Later, a pastor told me that a good friend of mine who had died hang gliding was burning in Hell because he wasn’t born again. If these people were the body of Christ, then Christ I could do without.
I also had to deal with my homosexuality. The Bible says gay people are evil. I know that I am not evil, so the Bible had to be wrong, at least in that instance. All I wanted was to love and be loved, and if the Bible says that that is wrong, then clearly the guys who wrote it were cruel.
In addition, the whole idea of a loving God creating a personal torture pit to torment sinners for all eternity is monstrous. Not even Hitler or Pol Pot were that cruel. Any god who loves the suffering of His creatures is a devil, not a god and is unworthy of worship.
