Another proof that we know nothing about the past civilization.
27 Giant sarcophagi (2m wide and 4m long) are located deep underground in the tunnels under the pyramid of Djoser.
The walls of granite sarcophagi are perfectly fitted and polished both outside and inside. They are made at the highest level, which is impossible to repeat even in modern conditions.
Another question arises at the expense of transporting hundred-ton sarcophagi because, in the narrow passages of the pyramid, a sufficient number of slaves could not fit to drag them there.
