The recent unearthing of a sea urchin fossil at the Giza pyramids and Sphinx complex has stirred speculation about ancient human civilizations. Could these renowned structures, marvels of ancient ingenuity, have once been submerged underwater? This long-debated theory has gained new support through a remarkable discovery by archaeologists Sherif El Morsi and Antoine Gigal, who found the fossil within the Giza complex. The physical evidence they uncovered lends weight to the hypothesis that the Sphinx and pyramids were underwater thousands of years ago. This finding echoes the controversial proposition by Dr. Robert M. Schoch in the 1990s, suggesting an ancient origin for these structures, possibly dating back to 5,000 to 9,000 BC. If this hypothesis holds true, it could significantly alter our perceptions of ancient Egyptian history.
