David "stole the fire"?

There is no real way of knowing which context the connection to Prometheus is. The Engineers was going to wipe us all out before David got his hands on the Urn anyway. It could be David, but then it could be Weyland.... It could also be the Engineers or at least those who created us who are Prometheus. There could be a number of ways to tie the movie to the Prometheus Myth. But the only ones i see as being Punished in this movie was/are the Engineers (LV 426 outbreak) and we all know the Xeno rips you open from the inside, and thats a fate the Engineer also suffered from the Deacon. But this punishment seems to be not by Gods, but put onto themselves for their meddling with the Fire? Maybe in context to this movie, the FIRE is not no Technology given or stolen by us, but its maybe the creation of us using said Technology.

Here's what the old Weyland said: [i]"The Titan Prometheus wanted to give mankind equal footing with the Gods. For that he was cast from Olympus. Well my friends, the time has finally come for his return."[/i] Weyland didn't want fire, but what he did want was immortality. That's the equal footing he was after. In that sense, he was simply equating himself with Prometheus. Christ only knows what would have happened had the Engineer actually granted him that wish. I suspect he may then have upped his ambitions a little.

My take on it is this. The Engineer is Prometheus. The engineers were punished. Weyland hoped that the Engineer would give us fire (black goo?) potentially immortality and equal footing with the Gods. When Shaw says "We were wrong, so wrong". I take 'we' to mean all the goals sought after by the Weyland expedition team.
