Water Erosion on the Sphinx — Implications

Geologist Robert Schoch (Boston University) argued in 1991 that the erosion patterns on the Great Sphinx and its enclosure walls are characteristic of prolonged rainfall, not wind and sand erosion. The vertical and rounded erosion profiles match precipitation-induced weathering. The Sahara has been arid since approximately 5000 BCE, meaning the Sphinx would need to predate this period by centuries or millennia to accumulate such erosion — potentially placing its construction between 7000-5000 BCE, thousands of years before the conventional dating of ~2500 BCE. If correct, this implies an advanced pre-dynastic civilization existed in Egypt far earlier than mainstream archaeology acknowledges.
