Not my own work but something I am using for a paper in my first level studies in Canon Law dealing with the Historical accuracy of the Book of Exodus:
Summary: Moses most likely wrote large parts of the Pentateuch as YHWH commanded him to (they spent a lot of time together up there on the Mountain, you know...). Those sections of the Torah or the Pentateuch were later arranged by subsequent editors who added additional material. Scribes passed this information down and further editing was made until we have the books we have that Jesus quoted from. The 19th century textual criticism is a bunch of bunk...but interesting bunk that is easy to discredit.
Although the author of Genesis is not identified in the book, its integral part in the Pentateuch (Genesis— Deuteronomy) suggests that the author of these five books was the same person. The books of the Pentateuch give evidence of unity through their common plot, theme (divine promises), central figure (Moses), and literary interconnections. Jewish and Christian traditions attribute the Pentateuch to Moses, whose life paralleled the events of Exodus— Deuteronomy (cp. 2 Ch 23: 18; Lk 16: 29,31; Ac 28: 23). Passages in Exodus— Deuteronomy testify that Moses authored diverse materials (Ex 17: 14; 24: 4-8; Nm 33: 2; Dt 31: 9,22). Although we cannot be certain about the contents of the "book of the law [of Moses]" (Jos 1: 7-8; 8: 31; 23: 6; 2 Kg 14: 6), its association with Moses established a "psychology of canonicity" that set the pattern of divinely authoritative writings (Nm 12: 6-8; Dt 18: 15; 34: 10). Scholars have usually recognized that minor post-Mosaic contributions must exist in the Pentateuch, such as the report of Moses' death (Dt 34). Some have contended that the first-person (" I") sections were written by Moses and that another author set them in a third-person (" Moses") narrative frame. Prior to the nineteenth century, the consensus remained that Moses wrote the essential whole, probably during the wilderness sojourn.
Since the events of Genesis preceded Moses, this raises the question of where he got his information. For most of the Christian era, the principal explanation was divine revelation coupled with the availability of written records, such as genealogies and stories. Gradually, though, by the nineteenth century, a new consensus arose among "critical" scholars. They believed that the Pentateuch was the product of a series of unnamed Jewish editors who progressively stitched together pieces of preexisting sources dating from the tenth to the sixth centuries b.c. Instead of being Mosaic, the Pentateuch was viewed as a mosaic. Such scholars today often view the stories in the Bible's first five books as fabrications conceived hundreds of years after the supposed events, perhaps during the exile. There is significant evidence, however, that Genesis reflects the political and cultural setting of the second millennium b.c. The structure and contents of chapters 1– 11 generally parallel the Babylonian epic Atrahasis (c. 1600 b.c.). Social and religious practices among the patriarchs correlate better with the earlier period than with the first millennium BC. For example, Abraham's marriage to his half-sister Sarah was prohibited under the Mosaic law (20: 12; Lv 18: 9). It is unlikely that the Jews of the exilic period would have fabricated offensive events or preserved such stories unless these were already well-entrenched traditions. Also the prevalent use of the El compounds for the name of God (e.g., God Almighty– El Shaddai, 17: 1) in Genesis contrasts with their virtual absence in first-millennium B.C. texts. The tolerant attitude toward Gentiles and the unrestricted travels of the patriarchs do not suit the later setting. The evidence, when considered as a whole, supports the position that Genesis remembers authentic events.
Genesis and Ancient Myths
The parallels between chapters 1– 11 and creation and flood myths have elicited the question, Is the Bible merely a Hebrew version of myths about beginnings? When weighing the importance of parallels, these principles should be kept in mind. First, not all parallels are equally significant, since minor ones can be attributed to common content. Second, the identity of who is borrowing from whom cannot be definitively concluded. Often it is best to assume a universal memory as the source. Third, the functions of the stories are much different. For example, the flood story of the Babylonian Gilgamesh Epic is incidental to the main idea of telling how Gilgamesh sought immortality. In the Bible, by contrast, the flood narrative is central to the development of the theme. That the Bible's theology is divergent from the polytheism of antiquity argues against the Bible's dependence on sources from other cultures. The author of Genesis was aware of the cultural context of the nations and often crafted his accounts to counter the prevailing view. The historical framework of chapters 1– 11 (e.g., "these are the records of," 2: 4; 5: 1) and the genealogies (chaps. 4– 5; 10– 11) indicate that the author presented a historical account, not a literary myth.
