Something else to consider...

The charge that biblical scripture is just a rehash of early ancient ideas and text fails to pass the sniff test if one delves into study of the polemic nature of Genesis against Babylonian/pagan culture and beliefs.

There are vast differences between the two belief sets and the text of Genesis was God's way of setting the record straight in the face of the rebellious and evil culture which dominated the age. He chose to have His "set-apart" Nation be the well-spring of truth and the vehicle to reclaim the scattered and lost nations of the world.

No one with a sense of truth and honesty could equate the Genesis account with the Babylonian culture after intense study of the obvious differences in the ideas of creation and origins between the two.
