I don't know about you but I had been reading about them being built by skilled laborers for at least 20 years. Archive: https://archive.today/mX8uV From the post: >>Archaeologists have uncovered ancient inscriptions inside Egypt’s Great Pyramid that they say confirm who built the monument 4,500 years ago. Ancient Greeks shared stories that the stunning monument was built by 100,000 slaves who worked in three-month shifts over 20 years. But new discoveries inside the Great Pyramid have changed the narrative, showing it was constructed by paid, skilled laborers who worked continuously, taking one day off every 10 days. Egyptologist Dr Zahi Hawass and his team recently explored a series of narrow chambers above the King’s Chamber using imaging technology, finding never-before-seen markings left by work gangs from the 13th-century BC.
