Ridley mentioned ages ago that the film would be about Gods and engineers, then we get the title "Prometheus", then we get a synopsis saying '...where they will discover the answers to our most profound questions and to life's ultimate mystery'.
So are we going to find out who created us? Or maybe that a vastly superior alien race has been influencing us on an evolutionary level, similar to 2001: A Space Odyessey?
What do you think?
