The dating of the Papyrus Ipuwer (which contains descriptions of phenomena obviously resembling or identical with the OT Ten Plagues) is known, but as it is a copy of the earlier original, the era of its original composition remains a little controversial. The 2nd IP fits the date of the Exodus and has grown in popularity, while a the 1st IP date was the original estimate, and the latter makes no sense at this point. Donovan Courville, in “The Exodus Problem and Its Ramifications”, proposed that the Exodus happened in *both* the 1st and 2nd IP, and that the two periods were simultaneous, but that isn’t based on much. The physical date of the papyrus that has survived is New Kingdom.

Scientists have identified a major climate crisis that struck Africa about 70,000 years ago and which may have changed the course of human history. The evidence comes from sediments drilled up from the beds of Lake Malawi and Tanganyika in East Africa, and from Lake Bosumtwi in Ghana. It shows equatorial Africa experienced a prolonged period of drought. It is possible, scientists say, this was the reason some of the first humans left Africa to populate the globe.
