So in short: Jesus was an Engineer, we fucked it up by killing him, our creators got mad and then hatched a really, really long and elaborate plan to kill us off. So in a weird way, "The Passion Of The Christ" could also be viewed as part of the "Alien" universe.... if you really think about it.... Or, after that, the Engineers simply abandoned humanity, we evolved, and they got pissed all over again when we came knocking on their door. But it pretty much fits in line with what Lindelof said during press rounds for the film: "I'm all for ambiguity, but if we didn't know the answer to that one, the audience would have every right to string us up. Yes. There is an answer. One that is hinted at within the goalposts of 'Prometheus.' I'll bet if I asked you to take a guess you wouldn't be far off."
While Lindelof has inspired anger in many quarters for being too oblique, we give him credit for at least erring on the side of contemplative mystery rather than spelling things out. Because what happens when it's all put down in black and white? It loses much of its power. The best films allow the questions to remain open, with the filmmakers allowing the audience to bring their own interpretations to it -- but Scott has ensured that won't happen by spelling it out. And Scott acknowledges the door was intentionally left open for a followup that would continue in this spiritual vein. But note, the Engineers aren't Gods. At least not directly.
"Well, from the very beginning, I was working from a premise that lent itself to a sequel. I really don’t want to meet God in the first one. I want to leave it open to [Noomi Rapace’s character, Dr. Elizabeth Shaw] saying, 'I don’t want to go back to where I came from. I want to go where they came from', " he explains. He adds: "I always had it in there that the God-like creature that you will see actually is not so nice, and is certainly not God."
So what are they? "In a funny kind of way, if you look at the Engineers, they’re tall and elegant … they are dark angels. If you look at [John Milton’s] 'Paradise Lost,' the guys who have the best time in the story are the dark angels, not God," he adds. So boil it all down, and humanity was the offspring of some dark/rogue angels? That would seem to be the gist of it, and we guess that's where a "Prometheus 2" would go if/when that should ever happen.
But can there really be a sequel at this point? The big mystery at the end of "Prometheus" is, "Why?" Lindelof has already teased that, "Now 'Prometheus' is ready to go off in its own direction on its own entirely different tangent that is not going to be reliant on the things we've seen a thousand times before." And that's fine, although it seems to us that the core driving force of the discovery of the "dark angels" makes it all kind of moot. Perhaps they were banished themselves for attempting to create life? And maybe humanity is a reminder of their folly? Again, a good theory, but do we want it explained away in another movie? Probably not.
"Prometheus: Guess What, Jesus Was An Alien!" is in theaters now and bonus: here's a pic of an Elderly Engineer from that opening scene that was deleted from the film (via Prometheus Forum). Update: Almost 10 Engineers appeared in that opening sequence.
