I don't know why everyone keeps wondering who REALLY built the pyramids...the answer is right in front of everyone's nose.
King Solomon had built the Temple...the Temple was constructed as Josephus and the bible and such tell, without the sounds of metal tools at the
temple site.
This is because the rock was cut and squared in the quarries, and the timber cut from Lebanon and floated down to Joppa and there at the Temple site
were put together with hard labor, using wooden tools.
Same goes for the Pyramids, only there are no surviving records of their construction, however Architecture and construction didn't change until much
later.
So the Pyramids would have been built very similar.
And not by slaves...they were built by the farmers duing the innundation periods.
So the stones would have been cut and prepared off site, and then floated down the river or across the mediteranean, to be placed by woden or stone
structures built for that purpose (the Pyramid is kind of its own scaffolding).
There may have been a few tricks we aren't thinking of, but over-all it would have been simple.
Today we over-complicate things.
