Religous parrellels...

From Shaw's perspective (Abrahamic), i think she believes she is going to Eden. As things unfold, she realizes that the seraphim and cherubim have all been killed or corrupted, and the serpent is still loose, or even in charge of the garden now.

And the goat gets sent to Azazel...

I have always thought that Giger's unique form of automatic painting offered glimpses into both the good and the evil spiritual worlds - beauty and beauty corrupted. I think that the idea of God creating angels then the fallen angels rebelling, Greek gods and their younger usurpers are closer than most people think. Weyland declaring that "We are now the gods." is not the kind of statement that God or a Greek idea of a god would ever let go unchecked. That is usually the kind of presumptuous mocking statement that coincides with the proverb "pride comes before a big fall." That's usually the precursor of bad things hitting the fan. Weyland has knowledge, but does he have wisdom as well? I suspect that Ridley Scott with play with both of these themes (Greek/Christian) with Giger illuminating the way with images that will totally blow us away. -They've certainly saved the best for the movie and I cannot wait.
