You may have heard of the documentary hypothesis, the theory that the Pentateuch was written by several different schools, J, E, D, P, B, and S. You may have also heard that this theory was advocated by Julius Wellhausen. However, that’s actually a myth that only superstitious dolts believe in. We modern educated people know that Wellhausen didn’t really exist. In truth, the books attributed to him were actually written by hundreds upon hundreds of different authors, and then randomly redacted and edited by The Worst Editor Ever.
And if you don’t believe this story, then you’re stupid.
