I agree, making sense of the whole thing would make a lot of us feel better, but I look at it this way: the Alien, AVP and Predator films are canon in the AVP universe, which excludes Prometheus. The Predator and Alien films are canon in the Predator universe, which Prometheus may or may not fit into. Only the Alien films are canon in the Alien universe.
That way, every timeline is sort of right as long as you know which iteration of the timeline we're talking about.
