    apparently ancient egypt had diamond tipped tools which could have turned granite on a lathe.

      Maybe, but also in a big granite sarcophag of more than 100 tons made in one piece? A lot of diamonds needed for this

      Serapeum of Saqqara

      Maybe they used another system

      Devices that could cause the high-heat needed, or any chemical substance unknown, able to liquefy the granite? The latter seems to me the most likely explanation, and the staircase suffered an accident with this substance.

          I don’t think so, people are too quick to explain everything with aliens, that the human being is much older than what was believed, it is much more probable and that there were already advanced civilizations before that have disappeared due to a cataclysm. The fact that they found skeletons of primitive hominids from 2 million years ago does not mean that they were all like that, before that there were many different human races and they may have existed in very different states of evolution.
