Quote from: Mike's Monsters on Today at 08:51:59 AMThe impression I got was that that DNA was found in the derelict ship we see in ALIEN. Not in building a new one. It hints at somehow humans and Xenos being connected in the past. How? I don't have that information.
Prometheus was out at the time. It's most definitely Engineer DNA which (according to that infamous bit in Prometheus) is a 100% MATCH with HUMAN DNA
considering that there's a lot of hearsay about this detail of the movie, i bet a lot's been misunderstood, lost in the telling.
What makes some sense to me is if the Aliens build (very durable) biomechanical material nests out of their victims - and it would make sense for the Engineers to see this as prized material, they would then go in, exterminate the aliens, retrieve the nests, insert their own tech in there and build proper SHIPS with it. It would maybe go some way to explain why there's a Deacon mural in LV223 - They worship these creatures and others of its ilk. It would explain why the derelict ships look "grown" rather than built, it would explain why the cave under the Derelict in the original movie looks like a technological/aesthetic extension of the Derelict ship itself (the aliens would've built that after the Engineers lose control of the situation).
