“Saqqara, in Egypt, is the oldest stone complex ever built by humans”
What’s the oldest stone complex ever built by non-humans?
I don’t know, but others might.
What I do know is that the Saqqara pyramid is younger than the pyramids at Giza according to unpublished and published reports by several teams of Egyptologists.The Saqqara pyramid is definitely NOT the oldest stone structure known - many megalith structures are far older.
There is also a optical thermoluminescence dating on one of the three Giza pyramids that puts its date at around 3500 BC - 5500 years ago.
The Saqqara pyramid was an attempt to imitate the builders of the Giza pyramids by a later Pharaoh. In fact, the whole of Egyptology as a history is in complete disarray - much of which is sue to the severe restrictions on actually studying many sites for any length of time, if at all - like the Sphinx Temple.
Dating tests of types which cannot be done in Egypt (like optical thermoluminescence due to lack of facilities) have been recently forbidden. Zwass strikes again.
Thanks for asking . . .
