[Kalyx triaD]

I have a feeling we'll see the xenomorph lifeform perfected in some way by the end of the movie, or it's development hinted at. We'll probably know for sure that they are weapons or some kind of 'galactic cleaning' measure like the installation rings in Halo.

My thing is these Space Jockies, or from what I guess... this one Space Jockey, fell victim to a facehugger. His fate is sealed from what we see in Alien. So are we gonna see a Space Jockey xenomorph as a final boss sort of deal? It must have been dealt with way before Ripley's crew found the ship, otherwise Kane and the others never would have made it out with some beast in there (assuming these things live that long without... whatever they eat to live).

Also, it seems like the Space Jockies been to Earth before. Aside from the obvious questions of whether or not they created us or assisted us in the past, what makes this Jockey flip out and wanna come to us with xenomorph cargo ("If we don't stop it, there won't be a home to return to!"). Did we do something wrong? Did the Prometheus crew do something wrong?

Prometheus paid a price for stealing fire (which Weyland likened to technology) from the gods. He also gave pause to mention of the invention of gunpower ("A game changer, that one."). There's hints that while Elizabeth and her guy are on an exploration trip, Vickers and David may be there for reasons closer to how Weyland-Yutani conducted themselves in the later movies. The android on Ripley's crew revealed that the company knew about the xenomorphs (or at least that there was something worthwhile on the planet).

Is the Prometheus crew's real mission to steal fire from the gods, only to suffer the mythological figure's fate? In this way Peter Weyland's viral speech was some sly way of giving the general events of the movie.

From what I see Weyland is ego-maniacal, and more than likely considers himself a god already. The Space Jockies would pose an interesting measuring stick for him, that I assume he probably would not accept. He would think nothing of sending a crew in to clean up that alien ship and claim anything found at the expense of his workers. Hell, this may be the true intent of the company's 'Building Better Worlds' colony expansion.
