The most devastating thing, though, that biology did to Christianity was the discovery of biological evolution. Now that we know that Adam and Eve never were real people, the central myth of Christianity is destroyed. If there never was an Adam and Eve, there never was an original sin. If there never was an original sin, there is no need of salvation. If there is no need of salvation, there is no need of a saviour. And I submit that puts Jesus, historical or otherwise, into the ranks of the unemployed. I think that evolution is absolutely the death knell of Christianity.
