Since neither Moses nor the actual experience of the Hebrew tribes in Egypt can be confirmed -- the rest of the story is not important, but as a political statement for the people reading it -- and of course, with Aaron-ist adding his name to much of it.

There's nothing to test. And, of course, the complete change of the old testament Christian edition, from the much earlier five books of the Hebrews, confuses what was written at all.

I do think that the "I am that I am" name of the Hebrew god is a step forward in religious thinking -- certainly the one-god theory is interesting, although even that is not necessary. As I recall, the English version of some of the early books does have a god that states you shouldn't worship the other gods -- wonder which ones ?
