A long (but detailed) speculation

Okay - this is something I've been working on and for those who know me, the podcast will be up at some stage shortly. This initial post concerns itself with the planet seeding scene as well as the symbolism of the title Prometheus. Prometheus is the Engineer at the beginning of the film The 'engineer' we see at the beginning of the film symbolizes “Prometheus” of legend. The myth goes along the lines of him creating man, in addition to giving him “fire”. There are several important things revealed in the opening of the film – that this 'engineer' sacrifices himself to seed the planet with DNA into the waters of this early earth. Could this possible be seen as a religious act by these engineers? Their 'biological weaponry” as seen later in the film would seem to indicate they can create lifeforms – why then would sacrifice be needed to seed the earth? Surely an alien race with genetic engineering capabilities of creating such biological weapons of mass destruction would be able to extract DNA and seed a planet without need for a living sacrifice. Religious sacrifice was a common practice by many ancient civilizations – and there are many visuals throughout the Alien ship that draw comparisons to the hieroglyphics found in many ancient tablets and walls etc. Even the discovery at the beginning of the film – where archaeologists find the “invitation” to set star co-ordinates establishes the fact that either (a) The engineers wanted mankind to find them when mankind had the technological ability to reach them or (b) ancient civilizations were doing their best to document history according to them; ie: it was not an invitation, just a bunch of guys pointing up to the stars saying “this is where the gods came from who made us.” Other similarities that would indicate early man 'copying' their creators can be seen in the some of the tech seen in the film on the alien ship. One example is the chamber with the head and urns in it. Ancient man would make offerings contained within urns to their gods including human sacrifices. There is also the sarcophagus shaped hibernation chambers – ancient Egyptians where buried in sarcophagus's and it was believed they would continue into the afterlife. A case of mankind imitating the technology of ancient aliens? The site where the alien ship is found looks very 'ancient' themed – a burial mound almost. Hieroglyphics are on the walls and David who has spent time studying such things can decipher these writings. Thus there is allusion that earth's language has evolved from these beings as well since the language that has developed over mankind's evolution has a relationship of sorts to the engineers themselves. It is certainly established that we share the same DNA. What we don't know is why he is seeding the planet – it is established that it is a different space ship in the sky than the horseshoe shaped 'military' ship of the engineers later on in the film. There are a few possibilities to consider: 1. This is a case of a rogue engineer from their society running an unauthorised experiment in an attempt to create life and become like a god himself. The gift of life to the planet earth involved his sacrifice due to his own DNA – something banned in his society or frowned on perhaps. 2. The seeding of DNA on the earth was simply an experiment to observe possible evolutions of human DNA. There were safeguards put into place in case the experiment went too long and this human DNA evolved to the point where humanity could travel to the stars and potentially replace/rival the engineers themselves. This invitation would lead to a trap designed to alert the engineers and therefore give them the chance to reset life on earth with the biological weapons on board their ship. 3. The sacrifice of the engineer seeding the earth may just be a religious sacrifice to the engineers god – the xenomorphs themselves. There is a statue of an alien with arms outstretched in an almost crucifixion pose – was this a statue of worship or perhaps only a sign to indicate what particular bio-weapon was in that area of the ship. It does have a religious feel about it. 4. There are a lot of dead engineers on board the ship found on the planet. There are holographic recordings of engineers running away from something that's got them scared. It's fairly safe to assume this is their own bio-weapons turning against them. If we consider the first ship seen in the intro of the movie is not the same design as the final alien spaceship, it is possible that their society has internal conflict within it. Could the bio-weapons they encountered themselves actually have been deliberately let out by opposition to killing of humanity? ..... discuss away, tell me what i may have missed
