It's amazing that people in this day and age try to go and "prove" that the fables, myths and allegories in the Old Testament are literal historical truth. You may as well go out looking for Cyclopses and Sirens on islands off the coast of Greece because they're mentioned in Homer's Odyssey.
Seeking such "proof" is simply, well, proof that these people have no faith at all.
You do have to wonder about how secure the belief in God is among people whose faith requires the literal truth of six day creation of a young Earth, a worldwide flood, Noah's ark, Jonah being swallowed by a whale, Methuselah living for 900 years, Moses parting the Red Sea, and so on.
The funny thing is, most preachers even state that a large part of the Bible is allegory or a lesson wrapped up in a story.
That's not to say there aren't good things in it; there are indeed many good things in it, but to take every word literally is silly. It is what someone gets from it that is of value, not the book itself.
For Job, even the Jews considered it a work of fiction, but one that taught a lesson so they kept it. There are other books in the OT as well that the Jews considered to be works of fiction as well.
So why do these modern people take it as fact when the people who wrote it considered it to be fiction? It boggles the mind.
Yes, I'll catch flack for such comments, but they are true.
