Do you believe in the Ancient Astronaut theory pushed by the series and by authors like Erich Von Daniken?
It's the theory that there were alien civilizations on Earth in ancient times in places like Egypt and Peru. Some go even further by saying that humans are hybrids and that these aliens mixed their DNA with the primitive life they found on Earth. They say it explains the missing link in the evolution of man and that 30,000 years ago we went from cave monkeys drawing on the walls with our own poop to intelligent humans with advanced scientific knowledge. They believe that we evolved natural from chimps but up to a certain point and then there was an intervention from higher beings. It would explain the dual nature of humans.
