Question 2

Revolt · Accepted Answer

Some people claim that aliens built the pyramids because they believe the ancient Egyptians were too primitive to create such complex structures. They also argue that no blueprints for the pyramids have ever been found and that moving the massive two-ton stones would have required advanced technology that the Egyptians did not possess.

Question 3

Question 4

What evidence contradicts the theory that moving two-ton stones was physically impossible for the Egyptians, and must have been done using alien technology?

Revolt · Accepted Answer

Archaeological evidence, such as the remains of quarries and ancient tools, shows that the Egyptians were capable of building the pyramids themselves. Evidence suggests they moved large stone slabs by placing them on sleds and pulling them across paths lubricated with oil or water to reduce friction. This specific process is depicted in tomb paintings dating back to approximately 1900 BCE.
