Christians need to accept the revelation of the God's creation - to wit: the earth. Science suggests that the earth is billions of years old and that life began as relatively simple creatures, with more complex creatures added as millions of years passed to the present day. The obvious gaps in the fossils record are consistent with the Christian theory of a progressive creation. This is an "evolution" of sorts, but has nothing to do with Darwinsim or biological evolution. Humans didn't evolve from monkey-men (aka mankeys), for example - humans were a separate and distinct creation, formed from dust, as Genesis 2:7 states. None of the created kinds evolve beyond their original kind, although microevolution obvioulsy occurs within each kind.
