The whole 'David inventing the xenomorph' storyline was utter shite in my opinion. It also doesn't really follow on naturally to the first Alien film. In the first film the space jockey (an engineer) has been killed by a xenomorph (which presumably burst out of it's chest), if that's the case then where did that xeno come from?
I'm pretty convinced that the beings David killed weren't engineers, they didn't look quite the same and they were basically living in mud huts with one landing zone. I think they were another seeded species.
plausible..... they way they were greeting the arriving ship was like worshipping a god or something.
