Shem and Yafeth

In Toledot HaShamayim v'HaAretz you will find how (what remains of) Parshat Noach is a perfect ending of the story. Noach brought two things to the world. He called upon the Name of HaShem, and brought sacrifices to Him, and he was the first to plant a vineyard. The Mabul, the flood, you will not find in the above document. It is largely an invention of the priestly editor, and that which seemingly is not, drowned in it. The end of the Toledot HaShamayim v'HaAretz concerns Shem and Yafeth, the J1 and J2 haplo-types, in modern parlance.
