Of Gods, Engineers & Men

After seeing the Prometheus (Part One) last night and reading a few theories from my fellow story lovers, here's my attempt at a possible explanation/evolution of the tale being told. This story is about creations destroying their creators. Let dive in... In the first scene the 'Engineer' is seen to commit suicide to create life on Earth. Simple? Im not sure. I think he has been delivered to Earth by a third race (the Gods) to act as a devotee/sacrifice and give himself to create life, for his creator/God. Not a great stretch, given the ship seen in the sky during this introduction is of an aesthetically pleasing design (ovoid/egg-like/life-bearing) not the hellish 'Devil's Horned' design we see later.  Design usually speak volumes about a civilization the kind of entities therein... And in this case the Gods are represented as life-giving, well-natured, enlightened, thus curvy ships. These 'Gods' have, in Earths distance past (up to 35,000 years), pointed to a LV233 and said "come when you are ready"... an invitation to enlightenment, instruction or possible 'transcendence'. Little do they realize that by the time Earth's offspring are ready, things have gone to hell on LV233 with another of there 'children' the Engineers (a devolution if you will).  Like all spoilt children, the Engineers have revolted against their parents and have overthrown/destroyed them using what powers/technologies they have been granted or which they have developed. Perhaps the 'black goo' is a weapon evolved from the original 'Earth-seed'. They may have done this out of spite. Spite for being used as sacrifices. Spite for being overlooked. Or possibly they have simple outgrown there parents. "who wouldn't want to kills their parents" (sic). Whatever the reason, the Engineers destroy their makers and install themselves as the New Gods. They erect idols to themselves and convince themselves that they are Devine, invincible and almighty. Having destroyed their own makers, the Engineers realize that offspring/subordinate lifeforms can come back to overthrow you, they decide to destroy the humanity, whom they were in part, responsible for creating. They know the atrocities we are capable of, they know we have almost unlimited power (we have now created David). They have been watching humans grows in faulting leaps and bounds during their visitations with their masters and they do not like what they see. They also know that eventually humanity will find out what they have done and might serve interstellar justice. But, within the Engineers there are factions and it is but one faction that wishes to eradicate humanity. And thus the infighting begins, resulting in the use of the 'Earth-seed' bio-weapon technology being released by the non-warrior (human-loving) faction on the warrior faction hell bent of destroying humanity. Thus the eradication of all 'Engineers' on LV233 (except for one that made it to the sleep chamber - think Ripley in Alien). When the last surviving Engineer is woken by David and they converse in private, we know David is given enough information to know the direction of another home world, but what else? Does David reinforce what the Engineer already knows, that humanity is dangerous? Does David, in fact, want to kill his maker? Whatever is said then and later when the team is there, we know the Engineer decides to carry out his original protocol and try and destroy the humans and return and finish the job on Earth. If this entire story is about the created destroying the creator, then it is highly likely that David may well be on a hell-bent mission to wipe out all Gods that have gone before him and instigate a pure zen-robotic evolution of higher beings, without emotion, without death and seeking pure knowledge of all that has been and will be. Wouldn't mind seeing that movie.
