They didn't spend all their time staring at their phones, typing with their thumbs, for one thing. They had a lot of time, and had a lot of time away from the fields because of their method of agriculture, once a year flood, and large food surplus.
There's a relief from the tomb of Djehutihotep that shows Egyptian laborers pulling a large statue.
One of the Ramses (II I think, his 83 ton statue was restored by Nasser, then moved about ten years ago from outdoor Cairo to the museum) learned of the death of one or more of the many people moving a huge statue of the pharaoh and declared his regret about the death(s).
The alternative is to claim, with no evidence whatsoever, that it must have all been done by someone else even longer ago, and none of their methods or technology has survived or been recorded anywhere. And that gets shaved into bits by Occam's Razor.
[snip] Diorite is an extremely hard rock, making it difficult to carve and work with. Its hardness, however, also allows it to be worked finely and take a high polish, and to provide a durable finished work.
One comparatively frequent use of diorite was for inscription, as it is easier to carve in relief than in three-dimensional statuary. Perhaps the most famous diorite work extant is the Code of Hammurabi, inscribed upon a 2.23 m (7 ft 4 in) pillar of black diorite. The original can be seen today in Paris' Musee du Louvre. The use of diorite in art was most important among very early Middle Eastern civilizations such as Ancient Egypt, Babylonia, Assyria, and Sumer. It was so valued in early times that the first great Mesopotamian empire -- the Empire of Sargon of Akkad -- listed the taking of diorite as a purpose of military expeditions. [/snip]

Well, I’m sorry. I must have misread your recent post on the Serapheum as allowing some doubt about the site being a middle kingdom tomb for Apis bulls because the technology and tools of that era didn’t seem possible to make those smooth surfaces and interior squared spaces in hard granite.
I suppose they could put a lot of workers outside and inside those boxes and use an infinite amount of time between lots of ‘box lunches.”
No evidence? I've been saying all along that there's NO evidence that even suggests the dynastic Egyptians built the megalithic structures in that country.
They documented every part of their lives in great detail, but there's nothing about building pyramids, or erecting colossal statues and obelisks. One small graphic of some men pulling a statue of some sort, is about the weakest sauce you could offer.
I asked before, what tools did the dynastic Egyptians use to cut, shape, and smooth the 70 ton granite blocks in the King's Chamber? How did they haul them? How did they lift them into place?
And how did they get a 13 acre building, composed of over six million multi-ton blocks, less than three sixtieths of a degree off true north? We can't do that today.
