"They apparently think that God could snap his fingers, and there was a new creature. But they don't think God could have created a life system that would modify itself over time. Creationism is such a simplistic view of God."
That is just a rationalization on your part. You are trying justify your own lack of faith in the reliability of scripture. What you call "simplistic" is what I call the simple faith of a child that Christ Jesus said was necessary.
What I am trying to communicate is that many different people, and many Christian churches, have different interpretations of the Bible.
We've long since quit chasing Quakers out of town, because all different views of God are tolerated. Except, it seems, those who understand the workings of evolution and see no reason to replace science with one particular narrow interpretation of Genesis.
