The central theme in Prometheus concerns the eponymous Titan of Greek mythology who defies the gods and gifts humanity with fire, for which he is subjected to eternal punishment. The gods want to limit their creations in case they attempt to usurp the gods. The film deals with humanity's relationship with the gods - their creators - and the consequence of defying them. A human expedition intends to find God and receive knowledge about belief, immortality and death. They find superior beings who appear god-like in comparison to humanity, and the Prometheus crew suffer consequences for their pursuit.
