Oldest pyramid in Egypt shows signs of hydraulic building technique
Briefly

Egypt's oldest pyramid, erected 4,500 years ago in Saqqara, could have been constructed using a sophisticated lifting mechanism, resembling a hydraulic machine, as per recent findings.
This hydraulic lift hypothesis suggests that ancient Egyptians incorporated water shafts into the construction process, enabling them to raise massive stone blocks effortlessly, potentially revolutionizing our understanding of pyramid construction methods.
