I didn't find that convincing in the slightest. We have ancient tablets that resemble the some parts of Genesis, but they are myths from other peoples, in other languages, with other characters, and other gods. The documentary hypothesis doesn't depend on any particular ancient recorded form, just that the text we have now seems to be constructed from multiple textual traditions or versions of some of these stories I don't think anyone has expectation that such texts could be found or that they are from the bronze age. (Then there is the gratuitous attempted parallelism between the "failing" documantary hypothesis and the "failing" Darwinian one.)
On the one had, I guess I could just say that I generally agree with you, but doing so seems like it would too easily wipe away the additional things that come to my mind here as I write this. So, I'll just say a few additional things ........................
I didn't post a link describing the Wiseman Hypothesis in order to be "convincing." Don't assume too much. My methodology of study is to cull from a WIDE array of sources from a WIDE array of positions, picking bits and pieces of interesting statements from all that is available. This way, I don't fall into the usual gutters of
confirmation bias.
I can remain open to culling a few thoughtful points from something like
the Wiseman Hypothesis just like I do from the varied positions derived from
the Documentary Hypothesis, or from
the Fragmentary Hypothesis or
the Supplementary Hypothesis. Or from any other scholarly hypothesis about the POSSIBLE literary, cultural and historiographical nature of the first 5 books of the Old Testament, as well as the rest of it.
Besides, you don't see me here saying that, "Oh boy, everybody, looky here at all that the evidence we have that corroborates the Wiseman Hypothesis!!! Oh goody, oh goody, oh boy, let's go !!!"
Yeah, that's not where I stand with things on the book of Genesis from my own (however limited) engagement with a swath of scholars from various sides.
