The problem here of course is that for the creationists, there is no argument. God did the lot. Even heard a woman on Vine today contest that fossils are so blimmin 'old' coz of the damage did to them during the biblical floods. Hmmm. Original, give her that.
I'm sure there are some scientists out there who don't think Darwin is totally right, but that doesn't mean just coz they don't believe in Darwin they must believe in God.
In a sense, Darwin has been one of the greatest gifts ever bestowed to the Xtians.
