Robert Schoch

Robert M. Schoch is an American associate professor of Natural Sciences at Boston University and a prominent alternative theorist in geology and archaeology. He received his Ph.D. in Geology and Geophysics from Yale University. Schoch became internationally known in the early 1990s for his controversial re-dating of the Great Sphinx of Giza, where he proposed that the monument's weathering patterns indicated it was built thousands of years earlier than the conventional dating of 2500 BCE. Using his geological expertise, he suggested that the Sphinx showed evidence of rainfall erosion, indicating it must have been carved during a much wetter period, possibly as early as 7000-5000 BCE. This hypothesis challenged mainstream Egyptology and sparked significant debate in academic circles. Throughout his career, Schoch has continued to investigate ancient sites worldwide, proposing alternative theories about human civilization's origins and development. He has authored numerous books and papers on these subjects, combining his geological expertise with archaeological investigations.
