Seems several sites agree that AE is only 2 years before Alien. And remember, both crews were in stasis for decades-long research missions. (Isn’t any light speed in this universe.) AE begins with the crew returning from a 64yr old mission. Hell, I’m assuming Earth doesn’t even know what happened to the Alien crew yet, given how far away they were, and lost contact. Maybe there is a Plot hole regarding Aliens. At that point (70+ years later), AE events should be known … unless AE series plans to have a plot about keeping the Xenomorph classified and secret.
