It is interesting to see how evolution is treated different by some in the Christian community as compared to other scientific theories. Evolution is inherently no more atheistic than the theory of relativity, the germ theory of disease, or the atomic theory of matter. The scientific method used to construct the theory of evolution is the same scientific method used in the rest of science: observe, hypothesize, test, report, repeat. Christians don't seem to have a problem with God enacting his plan for the world through natural processes like gravity and chemistry, so why would the natural process of evolution be any different?
Much, or maybe even all, of the conflict boils down to human tradition. At one point in history people latched on to the tradition that Genesis had to be interpreted literally in much the same way that human tradition saw the Bible as supporting Geocentrism. Through time, human tradition morphed into the "Word of God". Human interpretations were conflated with the actual book being interpreted.
The vast majority of atheists I talk to and know don't see evolution, geology, and astronomy as a problem for Christianity, and that includes myself. While scientists who are atheists might wonder why their Christian peers believe as they do, they have no problem respecting each other as peers and no problems understanding why evolution isn't a stumbling block for their fellow Christian scientists. If anything, atheists have a hard time wondering why some Christians would choose an interpretation of the Bible that is shown so clearly false by the world around us in the same way that Geocentrism was shown to be wrong more than 300 years ago.
