The Water Erosion Dating Revolution

Robert Schoch's geological analysis of the Sphinx erosion forces a timeline revision with cascading implications. If the Sphinx was carved before 5000 BCE (when the Sahara dried), and the Giza complex was designed as an integrated whole (Sphinx + pyramids + causeways), then either: (1) some structures at Giza are far older than 2500 BCE, or (2) the Sphinx predates the pyramids by millennia. The Inventory Stela supports scenario (2), describing Khufu finding the Sphinx already existing. If any Giza structures are 7000+ years old, this overlaps with Göbekli Tepe's active period, supporting the "lost civilization" hypothesis. The Sphinx sits in a quarry whose removed blocks account for parts of nearby temples — if the Sphinx is older, so are those temples.
