Ancient Aliens - The Mayan Legend of Kukulkan

History Channel series "Ancient Aliens" examines the Mayan rituals associated with the god Kukulkan and the temple built for him at Chichen Itza.
The Mayans do not speak about Kukulkan in a mythological context. They claim he was a real life being who descended from space and shared knowledge with the Mayan people.
Ancient astronaut theorists believe the legend of Kukulkan is one of many examples of ancient people being visited by benevolent extra-terrestrial beings.
