This is from back when it was an ALIEN PREQUEL. A lot of the plot and themes have obviously changed
MTV: Since this is a prequel, will you need to make the ships more primitive-looking than in "Alien"?
Scott: It's set in 2085, about 30 years before Sigourney [Weaver's character Ellen Ripley]. It's fundamentally about going out to find out 'Who the hell was that Space Jockey?'
MTV: And is the Weyland-Yutani company in existence at this point?
Scott: It's Weyland. Weyland hasn't joined Yutani yet, so they go and see Weyland. [The film] is about the discussion of terraforming — taking planets and planetoids and balls of earth and trying to terraform, seed them with the possibilities of future life.
