Evidence suggests the Sphinx is thousands of years older than officially dated.
The erosion patterns on the Sphinx enclosure are consistent with prolonged water flow, not wind and sand. Geologically, this suggests heavy rainfall - but Egypt hasn't had such rainfall in 7,000-10,000 years. That predates the accepted construction date by millennia.
The traditional dating places the Sphinx at around 2500 BCE, built by Khafre. But if Terra's geological evidence is correct, we're looking at a structure from the end of the last ice age - when a completely different civilization would have existed in Egypt.
But how do we reconcile that with the lack of other structures from that period? If a civilization advanced enough to build the Sphinx existed 10,000 years ago, where are the cities, the tools, the other monuments?
The head is proportionally too small for the body. It may have been recarved from an original lion's head during Khafre's time - explaining why the head shows wind erosion while the body shows water erosion. Different periods, different weathering.
Geologist Robert Schoch's work on this is compelling, but mainstream Egyptology hasn't accepted it. The challenge is that extraordinary claims require extraordinary evidence. We need more data points - cores from the bedrock, analysis of the restoration phases.
