Sphinx Schoch Position (10500+ BCE)
concept
A Boston University geologist argues water erosion makes the Sphinx thousands of years older than Egyptologists say.
Who they are
Robert M. Schoch, a geology PhD from Boston University.
What they do
The oldest-dating position, holding the Sphinx may predate 5000 BCE, possibly 10500+ BCE, based on water-erosion patterns.
How it works
His analysis of erosion on the Sphinx enclosure walls (from 1991 on) suggests it was carved during a wet, pre-dynastic era, and it comes through credentialed geology channels.
Why it matters
Alternative-history figures like Hancock and Tsoukalos use his work as a rigor anchor for lost-civilization claims, but the engine says his data-quality rating should be judged separately from what those popularizers do with it downstream.
The engine's record — word for word
Robert M. Schoch, Boston University geology PhD. Water-erosion analysis of Sphinx enclosure walls (1991+) suggests construction predates 5000 BCE wet period, plausibly 10500+ BCE during pre-dynastic pluvial. Tier-2 source-integrity (credentialed peer-reviewed-channel-adjacent geology). Hancock + Tsoukalos + alt-history-operator class cite Schoch as data-rigor anchor for lost-civilization claims. Engine framing: data-rigor verdict separable from operator-class downstream-distribution verdict per Whitney Webb Tier-3 discipline.
