The Great Sphinx erosion debate remains open, but the video's climate sequence and construction timeline are arguments, not established facts. The Sphinx was carved from natural limestone in the Old Kingdom quarry used for the pyramids and is conventionally associated with Khafre around 2500 BCE. Robert Schoch argues that water weathering reflects a wetter early Holocene and possibly a pre-dynastic date; that claim remains controversial. A 2023 NYU-affiliated study argued that wind erosion substantially shaped the body before human carving. It did not prove the video's humid-to-arid sequence, the central block's supposed flow-control function, or a single construction phase for the basin, temples and pyramid casing repairs.
Great Sphinx erosion theories remain disputed; Old Kingdom dating still dominates

Key facts
- The Sphinx was carved from relatively soft natural limestone left in the quarry used for the Giza pyramids; ancient quarrymen cut across the site's principal geological layers.
- Archaeology conventionally places the Sphinx and pyramid complex in the Fourth Dynasty, with the Sphinx attributed to Khafre's reign around 2500 BCE.
- Water and wind erosion are both proposed, but the claimed humid-first, arid-second sequence is not an established climate history for the plateau.
- Robert Schoch, an independent researcher, argues that water weathering reflects a wetter early Holocene and may indicate a pre-dynastic date. This interpretation remains controversial.
- A 2023 NYU-affiliated study modelled wind erosion and argued that it substantially shaped the Sphinx before human carving; it did not establish the video's broader construction timeline.
- The video interprets the basin, its central limestone block and pyramid casing work as a linked water-management and construction system. The cited sources do not establish a flow-control block, matching repair methods or a shared date for the basin, temples and pyramids.
- The claim that the Sphinx began as a naturally eroded yardang is the video's disputed interpretation, not established fact.
