How did ancient Egyptians transport the heavy stone blocks used to build the Great Pyramid of Giza?

The exact method of transporting the massive stone blocks for the Great Pyramid of Giza remains a subject of scholarly debate. However, the most widely accepted theory suggests the use of a large, sloping embankment made of brick, earth, and sand. As the pyramid grew, this ramp would have been extended. Stone blocks were then hauled up this ramp using sledges, rollers, and levers.1

It is also believed that the Nile River played a crucial role, with boats being extensively used for transporting stone from quarries to the building site. The construction likely involved a significant workforce, possibly around 20,000 permanent laborers, with additional seasonal workers contributing during the Nile's flood season.21
