Whole-genome ancestry of an Old Kingdom Egyptian

Egyptians don't like the notion that "they moved there from somewhere". They claim their own unique, uninterrupted, history and connection to the land as well as their civilizational independence from Mesopotamian, Asia Minor, Europe, and Africa.

It's also the same you rarely find Egyptian archeologists/scholars on scientific papers. While this might be a matter of ancient history and science to everyone, it's a matter of current day politics for Egyptians and especially the Egyptian government. The "findings" of the paper has to agree with the narrative built and proposed by the ministry of antiquities or they will literally charge whoever publishes it with a national crime.

It seems like Egyptian archaeologists is a clique of academics that do not like to rock the apple cart and go against established ideas about Egyptian history. There is a lot of gate keeping going on, mostly in part of Zahi Hawass, a narcissist that likes to self insert into every research into the subject, and control publication of results, etc. Even worse, claim attribution for work he's not even part of. So, if you don't kiss the ring, or dare to challenge ideas without his blessing, you'll be pretty much become a pariah that will never access archaeological sites again. Because of this, research in the field seems to be stagnant.

It's big business, has been for almost 5,000 years, and keeping the mysteries alive keeps the money flowing to the cult of Kufu or the modern equivalent.

History for Granite ( https://www.youtube.com/@HistoryforGRANITE ) touches on this powerful explanation for several observable aspects of these ancient sites that otherwise defy explanation. The top of The Great Pyramid was likely flattened so that rich visitors could pay to have an unforgettable picnic at the top. Many passages were filled up with sand and rubble because guides didn't enjoy the extra time and effort in hot dark bat infested areas that tourists demanded. And so on. Zahi is carrying on a long tradition.

I think you're confusing "Egyptian economic activity related to tourism" with "the existence of civilization in Egypt".

Djoser's pyramid seems to have been completed around a hundred years prior to that, and would have drawn crowds sufficient to warrant the large temple, grand entrance, and colonnades which are part of the complex.

There is a great deal of evidence that offerings provided by people traveling to these complexes sustained the religious orders on site who provided guardianship, maintenance, and worship. And that this was planned as part of the construction.
