The Pyramids were constructed by the Ancient Egyptians. That is to say, regular people built them with hand tools and very hard work.

The Ancient Egyptians built pyramids for tombs for their pharaohs and their queens.

All the Egyptian pyrimads were made ou of lime stone.
Aliens didn't build the pyramids, actual humans did that.
