I hate to be blunt, but the whole idea that Egyptians needed help from an advanced alien society, in order to stack rocks, comes from some wacko books from the Seventies, written by a racist who saw nothing unusual in white people being able to stack rocks without alien help (name one cathedral which any sane person thinks had to be built by aliens) but could not believe black and brown people could do so.
Aliens!
The aliens helped the Egyptians build it.
By Aliens.
The ancient egyptians build pyramids for the Egyptian pharoahs and kings.
Aliens didn't build the pyramids, actual humans did that.
The Egyptians built the pyramids as buril places for the pharoahs.

the Egyptians did.
The Pyramids were constructed by the Ancient Egyptians. That is to say, regular people built them with hand tools and very hard work.
