Aztecs and Aliens part 5

So many of these artifacts out of Mexico are very interesting and give us a good insight of what was going on during this time period although they do bring up many questions like... Did the Grey's help at all with any part of the Aztec, Mayan or even the Egyptian civilizations? Such as the building of their pyramids or temples and how they were placed to mirror certain star systems in the universe. Or were they there as gods to be worshiped and rule over these ancient civilizations? One thing is for sure, they were there.
