god darn that video was like entirely fluff
tldw: the theory is that they used normal ramps to build the bottom portion of the pyramid, but a series of internal ramps/channels to carry stone blocks up to the upper courses.

A third of the video was an Assassin's Creed ad
You may enjoy Practical engineering more
He's a civil engineer so his channel mostly focuses on infrastructure but occasionally he enters explores topics.
