The age of the Great Pyramids at Giza is disputed. The “official” age from the Egyptologists may be much too late. Curiously, those largest pyramids were built first, like they were built by an older more advanced culture, and the later ones are smaller copies of the originals. The great Sphinx at Giza also shows weathering from water, not wind, meaning the climate of Egypt has changed much since it was built.
A Optical Thermoluminescence date was obtained for the Menkaure pyramid of more than 3,000 BC.
Menkaure is traditionally believed to be youngest. This dating technique can only be analyzed outside of Egypt, but can no longer be done because all scientific dating methods by law must be done in Egypt.
Alternate water weathering on the Sphinx - the moat around the monument was filled with Nile water in the spring and the accumulated sand had to be dredged out, leaving behind erosion marks. There were annual processions around the Sphinx led by the then current Pharaoh and the priests. The remnants of docks are still visible on the southern side, as are the placements of various sluice gate hinges.
“Disputed”
Yeah, Hawaas is a train wreck embarrassment to the science of archaeology.
They can’t explain the megaliths either there or where they were found to be foundations for Roman structures (believed by ‘heretics’that the Romans simple repurposed the foundations, much like the cultures in South America).
They came even demonstrate the methods to produce the obelisks.
