The Pyramids and Sphinx of the Giza plateau are possibly thousands of years older than mainstream researchers suggest. In fact, these ancient structures could well predate the ancient Egyptian civilization by thousands of years.
Many researchers indicate there is enough evidence to suggest the Giza plateau was heavily flooded in the past. Interestingly, given the evidence found at the Giza plateau, the Pyramids and Sphinx could be some of the megalithic structures that survived the Great Deluge.
Researchers suggest that the Sphinx, the Temple of the Sphinx, and the first 20 fields of the Great Pyramid of Giza exhibit erosion due to deep water saturation.
