The idea that the Egyptians built the pyramids by rolling stone blocks on logs is a hypothesis, not a confirmed fact. While it is one of several theories about how the massive stones were transported, there is no definitive archaeological evidence to prove that this method was used. Other theories suggest alternative techniques, such as sledges or lubricated surfaces. The true methods remain a subject of ongoing research and debate among historians and archaeologists.

No. The pyramids were built by real people - the Egyptians.
because they believed in afterlife so they built the pyramids to put the dead kings in to keep them safe. In terms of grammar, both are acceptable. However, I would recommend using "Egyptians built pyramids" because implicit in the usage of the present perfect (the "have done something" tense) is that the action has continued to the present, which is not the case as concerns Egyptians building pyramids.
