No scathing comments. Perhaps my more literalist readers are just polite.
It does occur to me that I started in the wrong place. You play deity for awhile. You have a group of people who don't write, and you want them to remember what you've taught them over a few thousand years of history. How are you going to do it? You could, I suppose, insist they remember series of battles with Amalekites, Canaanites, and Assyrians. Like that worked so well even with written aids later?
You'd steer them nightly toward what we see in Genesis.
