How did Egptians carry such heavy stone to the pyramid site?

Answer 1

The limestone blocks were cut out in the quarries close the pyramid site. Once the limestone blocks quarried they were lowered onto sledges. Gangs of naked slaves dragged the sledge along a causeway laid with planks. Water or oil was poured in front of the blades of the sledge to help them slide more easily.

When they were building the Great Pyramid of king Khufu granite blocks weighing anything up to 70 tons were were floated over 400 miles from Aswan down the river Nile on rafts made from papyrus reeds. A canal connected the river with the pyramid site so the rafts could be brought as close to the pyramid site as possible. from here they had to be dragged on giant sledges to their location in the pyramid.
