Could Egypt’s first pyramid have been built by using hydraulics?

According to a new report out A water-powered elevator may have hoisted stones for King Djoser’s pyramid. The method by which they built the pyramid in ancient Egypt, using stones that weighed around 300 kilograms, remains a mystery that has puzzled experts for centuries. According to the study, a complex water treatment system using local resources might have enabled a water-powered elevator to lift heavy stones through the pyramid's internal vertical shaft. The study suggests that some type of float was used to raise the stones, however critics have already disputed these claims: Dr. David Jeffreys, a retired senior lecturer in Egyptian archaeology at University College London, explained that the more widely accepted idea is that the ancient Egyptians used ramps and haulage devices to move the heavy blocks. Many experts remain skeptical about the new theory.
