pre-prequal

the black stuff in prometheus is Dark Matter,this film is a pre-prequal,different planet different ship,it does'nt marry up with the 1st alien film,the next movie will i suspect take place on the ship which got away or maybe a rescue mission will land on lv-223,whp knows,looking forward to anyway and when all the films are done people will finally see that prometheus is in fact a very good film.
