IMHO, and this is as one of the resident heathens, theorizing as to how it happened is kind of counterproductive, right? I mean, if you believe in an all powerful creator, and that the Bible is His word....shouldn't it be a matter of faith? Just sayin....
As a dirty rotten heathen, I actually have alot of respect for people that believe in thier faith and don't try to come up with explanations for every little thing. Obviously, being educated and knoweldgeable about the faith matters.
