Immortality

Given what I have gleamed from the trailers and the viral campaign, I think that immortality, and its pursuit to be a central theme to this movie. First, examine Weyland Industries and its founder, Peter Weyland. Peter Weyland has the hubris, ego and resources to chase this dream. Weyland Industries spends inordinate amounts of $ on its health, electronics and cybernetics divisions. It is plausible that Peter Weyland has not been able to cheat death and hopes to do so with the Prometheus expedition and the use of extraterrestrial technology. It is this pursuit of immortality that places all of the events of Prometheus into motion. Second, examine what we know of the SJ's and engineers. There is not enough evidence to indicate that they still exist in significant numbers. Perhaps an explanation is that many of them have chosen to cease to exist. Immortality sounds great, but I can imagine that even supremely intelligent species losing the desire to live after a millennia or two. Perhaps, the SJ's and/or engineers require new species to "quicken" them, to give them a new impetus to live. Perhaps, they lay in wait for these new species to search them out by clues left all over the cosmos. Once discovered, these unsuspecting species are "infected" by the SJ's to serve as vehicles that will allow the SJ race to exist.
