Was Moses the probable author of Genesis?

P.J. Wiseman posits the theory that the 'toledoth' indicates authors who were eyewitnesses to the events mentioned in Genesis. This is based on the pattern of writing found on ancient Babylonian tablets predating Abraham where the word translated 'generations of' is used to indicate the ownership or authorship of the clay tablet.

He suggests that the pattern in Genesis indicates that Moses transcribed the text from tablets retaining these signature lines.

The tablets would have been passed down Father to son to Jacob, then to Joseph, who placed them in the library of Pharaoh where Moses had access to them. Whether it was Moses of one of Pharaoh's scribes who moved the text from tablets to papyrus is immaterial.

R.K. Harrison spoke favorably of the theory, and the Southern Baptist publishing house has used it from time to time.

The theory suggests that God himself wrote Gen 1, and some suggest the indication that Esau wrote Jacob's history, and Jacob wrote Esau's, is a problem, but then we marvel that their foibles are retained in the record.

Other popular views were well entrenched by the time of the discovery of the tablets prior to WWII.
