Prometheus turns that on its head. It's interesting that Elizabeth Shaw (Noomi Rapace) is a woman of faith; the events that unfold clearly challenge her, but the real implication is not about who came from whom (when she's mocked for her faith after it's proved that aliens, not god, created us, she simply replies, "Who created them?"), but the idea that we humans have a privileged place in the universe. Religious mythology in particular often reinforces this idea, like in the Biblical creation myth when God gives humans "dominion over the Earth".
But the "engineers" of Prometheus seem more like the gods of the Cthulhu mythos – not necessarily evil, but they've evolved so greatly, both biologically and technologically, that they are like demigods compared to us. We're like flies to them – an experiment perhaps, or perhaps even just one phase in an experiment. This is hinted at in a conversation between David and Charlie:
David: "Why do you think your people made me?"
Charlie: "[shrugging] We made you 'cause we could."
David: "Can you imagine how disappointing it would be for you to hear the same thing from your creator?"
To me, the most profound idea in Prometheus is our utter insignificance. And for me personally, it's a familiar one. As a non-believer, I think it's absurd to think that this unfathomably vast universe, expanding exponentially for 14 billion years and filled with billions of galaxies and sextillions of stars, was 'designed' with us in mind. The universe got along fine without human life for virtually its whole history, and the overwhelming volume of the universe is not only hostile to life, but will continue functioning just fine long after humanity has ceased to be. Special, we may be; but privileged... not so much. And as unlikely as it may be, it could be that there is, somewhere out there, a race of aliens that has evolved such that to us, they would seem like gods. Would such beings welcome us with open arms? Or would they swat us like flies?
Oh, and then there's this. Maybe it's just me, but I think that the orchestral theme for this film might just be good enough to be remembered as one of the great scores of film history.
