The Great Sphinx

Water erosion on its flanks, geologists whispered. Thousands of years too old.

The Sphinx water-erosion hypothesis — Schoch's geology argument that the enclosure's weathering pattern requires prolonged rainfall, pushing the carving back to 7000 BCE or earlier — was presented at the 1992 Geological Society of America meeting and remains a live minority position. Egyptology dates it to Khafre (c. 2500 BCE) on context. The dispute is why it links to Atlantis-era chronology and to the Hall of Records, which Edgar Cayce placed under its right paw.
