Ask AI: how were the pyramids built?

The pyramids were built by arranging blocks of stone and other materials into a stepped pyramid shape. To do this, teams of laborers had to transport the blocks and place them onto the pyramid. Some of the stones were shaped and smoothed at the quarry, while some were cut and finished after they had been transported. Many of the stones were lifted into place using ramps, levers and a system of pulleys. The ramps were likely made of earth, stone, and wood. Some scholars have proposed that workers used a sloping internal ramp to move the stones up the pyramid.
