If I take "Christian" literally, a follower of Christ, then I suppose it's possible to be a Christian who does not believe in a creator of everything. In my experience, Christians in general do believe that God created the universe and everything in it. This is completely incompatible with evolution. No living organism has ever been created in the religious sense of the term. If you don't get that, Keith, I'm afraid that your understanding of evolutionary theory is just as poor as your understanding of history.
