Christine Hayes, in this Yale Open Course lecture on the Hebrew Bible, examines Genesis through the lens of the documentary hypothesis. She opens by comparing the taming of Enkidu in the Epic of Gilgamesh to the second creation story in Genesis, then turns to Cain and Abel and its themes of the sanctity of human life and universal moral law. The bulk of the lecture compares Mesopotamian, Semitic, and Israelite flood narratives, tracing specific contradictions and doublets within Genesis 6-9, such as differing animal counts and flood durations. Hayes uses these repetitions, along with anachronisms in the text, to build the case against single Mosaic authorship of the Pentateuch and to introduce the idea of multiple underlying sources woven together. The lecture is part of Yale's Introduction to the Old Testament course, recorded in 2006 and freely available through Open Yale Courses.
