How old is the great sphinx?
The Sphinx's weathering pattern is the central contested data point — and it points far earlier than any pharaoh. Robert Schoch's geological analysis identifies deep precipitation-induced erosion that requires millennia of heavy rainfall Egypt has not seen since before 5000 BCE at the earliest. John Anthony West championed this reading, pushing the construction window back to at least 7000 BCE, possibly as far as 10,500 BCE. The conventional 2500 BCE date rests entirely on stylistic association and temple stratigraphy — not a single inscription names the builder.
Evidence
- Robert Schoch, a Boston University geologist, presented his water-erosion hypothesis formally at the Geological Society of America in 1992.
- John Anthony West, drawing on the earlier intuition of R.A. Schwaller de Lubicz, pressed the date toward the end of the last Ice Age, correlating the Sphinx's leonine form with the precessional Age of Leo (circa 10,970–8810 BCE).
- Anthropologist and author Graham Hancock has consistently argued that the absence of a dedicatory inscription on the Sphinx — unique among major Egyptian monuments — leaves its authorship legally open.
- Schoch has since updated his estimate using seismic subsurface data suggesting the Sphinx sits atop deeper, more heavily weathered bedrock, potentially indicating an even earlier sub-surface phase of carving.
- His core argument: the vertical fissures and undulating erosion profiles cut into the Sphinx enclosure walls are the signature of prolonged precipitation weathering, not wind-blown sand.
