The Unauthorized Version is a very well-researched book. The author studied ancient Greek, checked out the archeology and any contemporary - with the times spoken of in the Bible - writings by other historians, and any other evidence that could be assembled. He even got over-flight topography studies to show true or false about sites in the Bible of various events. That is the purpose of his book, to go over what was mentioned that could be true, and what could not. He also studied the publication theories of the time - a type of reverse plagerism. To get love poems, erotic ones at that, or other works kept in the manuscript, many authors attributed them to Solomon or Moses, or another famous prophet. The book was seriously edited at least a few times, but the last was well before the last older written texts - the Dead Sea Scrolls, or any others were translated.
Look for it in the 0-100 section of your library if it is on the Dewey. There is also Issac Asimov’s Guide to the Bible which may prove interesting. I couldn’t slog through it.
My basic working theory is that energy and matter are neither destroyed nor created, they just exchange form back and forth. Therefore, I get recycled. Fine with me. I carry a donor card.
