Did human civilization begin 5,000 years ago (as we are told) with Sumer and Egypt? Or is there more to the story? What was the actual purpose of Stonehenge? Why is the Great Pyramid aligned to true north? Is it possible that advanced civilizations predated the modern era by tens of thousands of years? If so, what happened to them? Today, Academia and Egyptology remain hamstrung by limiting beliefs, false assumptions and shallow readings of ancient texts. Mark Gaffney’s book presents compelling new evidence in support of Charles Hapgood's theory of crustal displacement, first introduced in the 1950s. Deep History and the Ages of Man introduces a new and exciting earth climate model that will challenge everything you thought you knew about ancient history.
