Dr. Robert Schoch goes over the evidence of intentional burial (youtu.be) in his talk at Cosmic Summit 2024.
That whole talk is interesting. Dr. Robert Schoch was among the first group of geologists to date the Sphinx. The Sphinx is much older than archaeologists say it is.
It would've took more time and man power to bury the place than to build it. It was covered over due to a natural disaster between 2600 and 2200bc.
