The Bible is a novel, just like Harry Potter, The Wizard of Oz and any other fantasy novel out there.

If you were to destroy all literature and 1000 years from now a Harry Potter book was found, he would be the new Jesus Christ. That's just how people are. They need to know that they are the center of things and that there is something waiting for them after death so that they don't lose all hope in life. Without that, the weak minded will fail.
