In Alien vs Predator it is revealed, that the aliens are an ancient race that for at least hundreds or thousands of years are the greatest prey for the great predators. Alien vs Predator is set in the late end of the millennium.
Now with the new plot from Alien:Covenant, the alien race is merely demystified to just a science project by some synthetic dude, made up of a weaponized genetic mixture.
Is AvP just a setting outside of the canon of the alien universe? Why is it, that the race has been demystified in any case?
