All right. I'm going to take on the part of the Devil's Advocate here and speak in favour of Christainity. Just this once.
Yes, the Bible is meant to be the Word of God, etc, etc. BUT, do you think it was really meant to be taken literally? In the times that the Bible was written, stories and analogies were often used to educate the masses. When something is put into a certain context, it is often eaiser to understand. Think of Jesus and his parables. The stories in the Bible may have only intended to have been an attempt to explain the values/beliefs/etc of Christianity, in such a way that it can be easily understood. That doesn't mean that they have to be taken literally.
As my Studies of Religion teacher once put it, the Bible was probably intended to be a 'manual' on how to go about living a Christian life. It wasn't intended to be an accurate historical record of anything.
