Some assumptions I've seen that should be challenged

I've been reading these posts on this board for some time now, as it's the best site I've found for clips and pictures and great discussion. I had some trouble registering but now I'm here :) However, I've seen 2 major 'assumptions' that I don't think should be taken as true, especially given the newest IMAX trailer content. 1. A lot of the discussions on possible plotline/plot points seem to assume that the trailers are showing clips in the order they appear in the movie. While it's true a lot of movies lately give the "Cliffs notes" version of the movie by doing this, I don't believe Mr. Scott is showing a synopsis of the film in these trailers. We are seeing bits in piece snipped together, but I don't believe any of it is in the order it happens in the movie. While the 'discovery' on earth of the pictograms, and the resulting trip is obviously the beginning of the film, all the 'action' sequences are most likely mashed up in a different order than they occur in the film. I'd even venture that the blantant 'off sequence' order of the IMAX trailer was done in an effort to point this out, for those that might not go see the film because they assume they know what is going on (showing Vickers with the flame thrower in the first few seconds). Secondly, while there is some heavy symbolism possible with the title of the movie, and the tie-in with the TED talk regarding the myth of Prometheus, I also do not think the creator of this film would be so heavy handed as to have Mr. Weyland so focused on the concept of Prometheus as the man punished for taking fire from the gods, and then having a SHIP named that to go on an expedition to have an analogous occurance happen to those involved. It is more along the lines of what George Lucas would do - and then have a character say "Look, that creature - it eats it's way out, and then heals the victim - just like the myth of Prometheus. That's the NAME OF THIS SHIP!". While I am sure this won't happen, any forced overlay of the myth onto this storyline would take a lot of coincidences, and it would just be soooo overly predictable to do this, at least in my opinion.
