This was the linchpin in my exit of the wits and belief in religion in general. No Adam/Eve. No original sin. No kingdom promise. No Armageddon.
Most mainstream religions treat Genesis as a myth or allegory. I'm not sure what theological gymnastics are involved in integrating that into whatever belief system they have. Sorry, as I've written, I pretty much gave up on religion. I admire the fact that they don't just deny science the way the wits and other fundamentalist crazies do.
It seems to me that evolution and the Genesis story are really two different subjects. Adam and Eve are mythical and the tribal accounts of the Hebrews are mostly the fictionalized histories that have woven themselves into the life and belief systems of Christians and Jews.
Evolution on the other hand, addresses the more generic (and scientific) question of how life began.
Just my two cents.
