The unknowns of pyramid construction chiefly center on the question of how the blocks were moved up the superstructure. There is no known accurate historical or archaeological evidence that definitively resolves the question.
How was the Great Pyramid built?
It was built by quarrying an estimated 2.3 million large blocks, weighing 6 million tonnes in total. The majority of the stones are not uniform in size or shape, and are only roughly dressed. The outside layers were bound together by mortar. Primarily local limestone from the Giza Plateau was used for its construction.

Could humans have built the Great pyramids?
A little over 3,800 years ago, humankind began to build the tallest structure ever known to the world until then—the Great Pyramid of Giza. Humans managed this feat without any modern technology or tools, using only ramps, ropes, levers and sheer muscle power.
