History
So if the ULT fits the geological and paleoclimatological evidence far better than the CET, why has the C.E.T. become ubiquitous in Egyptology? In a word: Christianity. Egyptologists were divided into two camps during the late 1800s, some supporting the long timeline, and others supporting the short timeline. The long timeline proponents based their views of Egyptian history on the ancient records of Egypt, while the short timeline proponents based their view of Egyptian history on the version of the Bible they were using at the time. The pattern was identical for Iraqi, Indian, and Chinese history, where the dates of the ancient Mesopotamian, Harappan, and the early Chinese civilizations, were all simply moved to after the Great Flood. The Great Flood is a story from Jewish folklore, in which a massive global flood was once sent by one of the ancient Jewish gods, to massacre all of humanity and some rebellious angels, that were living on the planet at that time, along with a group of giants, the angels had made by impregnating human women. There are dozens of known versions and variations of the story found in the early Christian, Jewish, and Gnostic texts, however, one was adopted into the Christian Bible, and so Christian fundamentalists need for all of history to conform to the Biblical timeline, or accept that the writers of the Bible weren’t omniscient.
