Yeah, theistic evolution; the idea that God created the process of evolution. The thing is that it contradicts the idea that God created us in exactly the same form that we are in now (i.e. the Adam and Eve story).

So if Adam and Eve never existed, and they did not "fall from grace", or lose complete innocence and commit the "original sin" by eating the apple from the tree of knowledge, then there doesn't seem to be a point to Jesus sacrificing himself for our "sin".

So with theistic evolution taking apart the whole point of Jesus Christ, where does that leave Christianity?
