The concept that life was planted on earth by super-intelligent extraterrestrials, a concept known as directed panspermia (popularised by the question, Was God an Astronaut? as written about by Erich von Däniken, amongst others)has been revived recently with the film Prometheus by Ridley Scott, and will no doubt be aired again when the sequel is released.
