A couple years ago I realized that I had somewhat subconsciously made the same assumption. The thing that snapped me out of it was my awe in watching Clickspring (YT) try to recreate the Antikythera Mechanism. That device's complexity and craftsmanship is proof to me that despite the lack of technology, there were some astonishingly smart and resourceful people living thousands of years ago.

The Obelisk at the Vatican weighs in at 360 tons. And was moved from Egypt to Rome by the Romans around 40AD. And then moved to it's present location in the 1586. The Romans moved at least 8 Egyptian Obelisks to Rome and also commissioned a couple.

The only thing really amazing about the pyramids is how many couple of ton blocks they carved out and transported. It's around 250 blocks a day for 25 years.

A thing of note, the Nile banks have been one the most fertile arable land around the whole mediterranean, that's why it was invaluable to the roman empire. Why it matters is that only in a place where you have very fertile land can you afford to have sooooo many people not working in agriculture and feed them to work for your tyrannical pet project
