A documentary, known as The Pyramid Code, claimed that the evidence about the existence of aliens that utilized advanced technology, in order to construct the Great Pyramid of Giza, is quite evident.
However, why we were taught that human beings had the responsibility for constructing the Egyptian pyramids? Despite the proofs, we don’t have the tools for building; this is constantly taught as a fact.
The host of The Pyramid Code, named Dr. Carmen Boulter, said that the proofs are in our hands. The human civilization was not capable of building such ancient wonder in the world. Hence, there was probably another civilization that took responsibility for this, maybe an alien one.
