"There’s a ton of archaeological and internal/external evidence for the truth of the Bible."

There's a ton of archaelogical evidence that many people and places mentioned in The Bible actualy existed, and generally fit the timelines suggested in the text.

"So how DID it come to exist?"

I don't know. But I do know that the Hindus are certain that Brahma did it. The Greeks credit the Titans. The Aztecs assert that we're on our Fifth Try.

Do you believe in Vishnu? Zeus? Quetzacoatl? Me either. I just go One God Further.
