The Great Pyramid of Giza has puzzled people for thousands of years. How did ancient Egyptians build such a massive structure without machines? In 2013, archaeologists found the Red Sea Papyri at Wadi El-Jarf, a port on Egypt’s Red Sea coast 240 km from the pyramid. These ancient documents include journals by Merer, a chief overseer involved in transporting large limestone blocks for the pyramid. Merer's detailed diary reveals a military-like schedule with his 200-man team moving stones from the Tura quarry to the pyramid every day. This discovery challenges old ideas that slaves built the pyramid. Instead, skilled workers were paid with bread, meat, and beer, and the project was supervised by elites like Pharaoh Khufu’s half-brother Ânkhkhâf. The journals show a high level of planning, coordination, and project management, making the Great Pyramid not just a feat of labor but an example of advanced organization in ancient times.
