How do you know the Jocks see themselves as superior?
They create the human race, so we are their little ant farm. Come on, of course they see themselves as superior. They ARE superior!
How do you know the Jocks are planning genocide?
Man, did you saw the same movie than i saw?
1- The engineers create human race
2- They came back here several times to teach us
3- We became evil
4- They send another emissary to teach us one last time (Jesus, as Ridley Scott already said)
5- We kill the emissary
6- They finally give up the humanity (we are a fail experiment) and they HAVE TO kill us all
Simple like that.
