Old news, and it didn't take AI to find it. German textual criticism found evidence of multiple authors for the Pentatuch in the 19th century.
Right, but wrong. Nothing can be proven, because every scribe adds and takes away, even in just the style and interpretive choices. Likewise the accusation that Moses could not have written in his own death. Well, of course he couldn't. Doesn't mean that one of his sons couldn't have picked up a pen and wrote an addendum...
As a fan, I think Contexual and Textual Criticism are often too big for their britches, Jussayin.
