Combined with the notion that the Stargate is a secret, "Stargate" productions are notable for presenting no contradiction with reality, being set in the present day on an otherwise normal Earth, and being dominated by human interaction in the galaxy. In the story of the 1994 film, this is explained as being the result of forced deportations by aliens, with the suggestion that most ancient mythologies are the result of aliens posing as gods in the distant past (as in unproven ancient astronauts).
