In this class Dr. Keislar first compares the timelines of ancient Sumerian texts with those derived from modern Western academic science and from current secret space programs. He finds that agreement between these sources may be good evidence that there is truth in them. The key dates he notices are about 500,000 years ago for a major solar system catastrophe resulting in the creation of the asteroid belt, 200,000 years ago for the appearance of Homo sapiens and 13,000 years ago for a major terrestrial cataclysm likely centered in or particularly affecting Antarctica.

After this, Dr. Keislar continues his study of the relationship between ancient Mesopotamian accounts and Biblical developments. He moves onward from the obviously related stories of the creation of humanity and the great flood that he discussed in earlier classes to wonder why and how the Hebrew prophets developed their concept of monotheism along similar lines and about the same time as the Assyrian and Babylonian traditions. Dr. Keislar plans to explore this challenging question further in the next class.
