Ancient Egyptians reportedly built the Great Pyramid at Giza by shifting more than 154 million kilograms of limestone in boats.

Archaeologists working with a documentary to be screened on UK’s Channel 4 claims to have unearthed an ancient scroll, a network of waterways and a ceremonial boat, The Sun reports.

The papyrus scroll is believed to date back to 2600BC and is said to be the only firsthand account of how the Great Pyramid was constructed.

The evidence claims to prove thousands of workers helped move 154,221,406kgs of limestone along the River Nile in boats made with planks and rope.

The Sun reports the limestone blocks were transported through the waterways before arriving at a purposely built inland port.

“We’ve outlined the central basin, which we think was the primary delivery area to the foot of the Giza Plateau,” archaeologist Mark Lehner said.

The Great Pyramid, which was the tomb of Pharaoh Khufu, was built in 2600BC.
