The particular reference to Egyptians is a red herring, since nobody else built pyramids of this sort (that survive and are known). I expect that if they were located in China or Europe (and no where else), people would equally wonder how the Chinese or Europeans could have been so unique as to build something of the sort.
I don’t think it’s very narrow to note that the Pyramid of the Sun was built with stones that a single man can carry on his own. It’s impressive at half the size of the largest Egyptian pyramids, but it doesn’t really raise the question of how. They just got a lot of people to carry a lot of stones, maybe using carts or something.
The Egyptian pyramids easily make one wonder “How did people move such large stones?” I could never move those with strength alone. Some form of technology / leverage / something was needed for the Egyptian pyramids which wasn’t needed for the American ones.
Some of the Pyramids were the largest structures in human history until the industrial age. They're definitely worthy of being considered their own category.
