Around 5,000 years ago, Egypt’s Great Pyramids were likely built using advanced organizational skills and manpower. Workers, possibly skilled laborers and farmers during the Nile’s flood season, used ramps, levers, and sledges to transport and place massive limestone and granite blocks. Copper tools and precise surveying techniques enabled accurate construction, reflecting the Old Kingdom’s wealth, engineering prowess, and centralized authority under pharaohs like Khufu. | Historyinmemes
