The Alien Architects (S12E04)

Numerous ancient architectural wonders exhibit remarkable similarities, despite being constructed by civilizations that were distanced by thousands of miles and likely had no interaction. For instance, the Giza pyramid complex in Egypt and the Avenue of the Dead in Mexico, over 7,500 miles apart, both feature pyramids aligned with the Orion constellation. Additionally, the ancient temple Baksei Chamkrong in Cambodia closely resembles the Temple of the Jaguar in Guatemala. Many of these structures utilized massive stone slabs, some weighing over a hundred tons. How did these early societies accomplish such incredible achievements? Could these remarkable sites have been the work of extraterrestrial architects?
