Living near Rendlesham I've always been struck by how much local history gets buried or forgotten within just a few generations, so imagine what gets lost over thousands of years. The Egyptians themselves wrote about earlier golden ages and "zep tepi" - the first time - which suggests they absolutely believed something significant predated them. Whether that was a real advanced civilisation or just mythology is the argument isn't it.
What gets me is the Inventory Stele at Giza which implies the Sphinx was already ancient when Khufu was around. Mainstream Egyptology basically dismisses it but you can't just hand-wave primary sources away because they're inconvenient.
Anyone looked into the subterranean chambers and water erosion evidence in any depth? I think theres more to unpack there than most people realise. Would be interested to hear what others think, especially if anyone's done serious reading on Schwaller de Lubicz or the geological arguments.
