The hypothesis about three sources of the Pentateuch of Moses (Book of Genesis) is considered: the Revelation of the Covenant on Mount Sinai, the Tables of Noah about the history of the antediluvian patriarchs and the Sumerian epics (which could have come to Moses through the descendants of Abraham, who was born and lived the first 72 years of his life in Sumer , in the city of Ur). The author suggests that it is the Anunnaki who are referred to in the original Hebrew of Genesis as "elohim" ("gods" in Hebrew), and, following Zecharia Sitchin, the author suggests that the "Nephilim" mentioned in chapter 6 of the original Hebrew of Genesis , are the children of the Anunnaki from earthly women. Until the 2nd millennium BC. It was their children from earthly women (i.e., the Nephilim) that the Anunnaki appointed as kings in Sumer and pharaohs in Egypt. The author refutes the opinion, widespread among some readers of Zecharia Sitchin, that the Book of Genesis is “plagiarized from Sumerian myths.” The last chapter (“New Hypothesis of Anthropogenesis”) is taken from another book by the author (Sumerians and Anunnaki: Anthropogenesis).
