So one answered question is that lin likes the dark meat
That question has been answered.
The facility was a bioweapons plant, which was answered by TPG. Why they want to destroy is us because we are an experiment gone awry, and are getting dangerous, especially with the new predator technology we obtained after AVP:R. The alien never got into the spaceship flight deck, he was alive because he wasn't woken up from cryostasis state. David did that because he was told to "try harder" and to see if the black goo had any ill effects on people before he gave it to his master/father. As far as where the Xenomorph that killed them went? It could be anywhere in the facility, they only explored a fraction (granted, they did have those red ball things that could apparently detect life), or any place on the entire planet/moon. It's also fairly unimportant to the plot.
Spoiler: show
also I didn't read any further than the quoted post
How are there queens if no humans ??????
Sorry howie, I don't see that happening at all. The engineers with skullfuck the android and Dr Shaw into oblivion the second they land on the planet.
Supposedly, it fits, I haven't really seen AVP:R and tbh I don't remember much of anything from Alien/Aliens. Something about at the end of AVP:R, the Predators left some technology, which allows humans to make the insane technological/medical advances seen the movie (Prometheus space ship, the medical things). Also, it could be that the engineers are making these bioweapons to fight another alien race (Predators), considering that Humans are/were hardly a threat to them (And thus, they want to destroy humans because they killed their "jesus" or whathaveyou).
Well, I was talking about him saying we were the missing link between Xenomorph/Queen and black goop. We still haven't seen if Xenomorphs can be born with only Engineers available to infect (unless this was covered in the Alien/s movies?)
Who says the predators are weaker than the Engineers? They could be trying but haven't been able to develop something which will do so, hence the bioweapons facility (which existed over 2000 years ago, coinciding with the first evidence of the Predators being involved with humans).
I like to pretend Alien, Aliens and Prometheus stand alone in their own little universe and then theres a separate one with the Predators and AVP. And finally, Alien 3+4 don't exist.
Nobody said that. They are far beneath them on the technological advancement scale though. What with them being so tribal still and locked in wars with each other, and they have not been able to create life.
I could be incorrect but the pyramids predate the last notation of the engineers. Visiting or at least being documented with a message to visit a certain system.They could be trying but haven't been able to develop something which will do so, hence the bioweapons facility (which existed over 2000 years ago, coinciding with the first evidence of the Predators being involved with humans).
Also correct me if I'm wrong but they have defeated at least one species by using aliens, what with the spaceship in alien being a bomber used in an ancient war.
If aliens were created in Prometheus how do they exist in avp? They have to be separate universes
