Meanwhile, another Ancient Aliens mainstay, Erich von Daniken, the "father" of the ancient astronaut theory (despite not having invented it), received glowing praise on Open Minds Radio's website for his role in inspiring Ridley Scott's new movie, Prometheus, which will use von Daniken's ideas as background for alien-human interactions in the universe first created for Alien. This is not the Alien franchise's first foray into ancient astronautics; Alien vs. Predator used the same idea last decade. The problem isn't so much that Scott is using a fringe theory for his fiction (after all, that's what H. P. Lovecraft did in his stories); the problem is that Scott appears to believe in the theory and will use the marketing machine for a major Hollywood release to promote the ancient astronaut theory as something that is true.
Ancient astronauts are an evocative idea. H. P. Lovecraft got great mileage out of that fringe theory and elevated it to the level of literature (and forty years before von Daniken). But he was always careful to assure everyone who asked that there was no truth to his fictions whatsoever. Less scrupulous showmen have no such compulsion to uphold the value and sanctity of truth, and as a result falsehoods get passed off as truth. Even dead Cthulhu would roll over in his undersea tomb.
