Now, consider the opening sequence of Prometheus. We fly over a spectacular vista, which may or may not be primordial Earth. According to Ridley Scott, it doesn't matter. A lone Engineer at the top of a waterfall goes through a strange ritual, drinking from a cup of black goo that causes his body to disintegrate into the building blocks of life. We see the fragments of his body falling into the river, twirling and spiralling into DNA helices.
Ridley Scott has this to say about the scene: 'That could be a planet anywhere. All he’s doing is acting as a gardener in space. And the plant life, in fact, is the disintegration of himself. If you parallel that idea with other sacrificial elements in history – which are clearly illustrated with the Mayans and the Incas – he would live for one year as a prince, and at the end of that year, he would be taken and donated to the gods in hopes of improving what might happen next year, be it with crops or weather, etcetera.'
Can we find a God in human history who creates plant life through his own death, and who is associated with a river? It's not difficult to find several, but the most obvious candidate is Osiris, the epitome of all the Frazerian 'Dying Gods'.
And we wouldn't be amiss in seeing the first of the movie's many Christian allegories in this scene, either. The Engineer removes his cloak before the ceremony, and hesitates before drinking the cupful of genetic solvent; he may well have been thinking 'If it be Thy will, let this cup pass from me.'
So, we know something about the Engineers, a founding principle laid down in the very first scene: acceptance of death, up to and including self-sacrifice, is right and proper in the creation of life. Prometheus, Osiris, John Barleycorn, and of course the Jesus of Christianity are all supposed to embody this same principle. It is held up as one of the most enduring human concepts of what it means to be 'good'.
Seen in this light, the perplexing obscurity of the rest of the film yields to an examination of the interwoven themes of sacrifice, creation, and preservation of life. We also discover, through hints, exactly what the nature of the clash between the Engineers and humanity entailed.
