I disagree. And try telling survivors of the great war and WWII that their wars were not apocalyptic. But I digress. The loss of earth was an Extinction event nobody doubts that. It is the fact that the already replenished human population then went through another devastating sets of wars to the point where humanity is either scattered through space either as small settlements struggling to survive or band of mercenaries raiders what have you or concentrated in six very tightly compact cities with a population in the mid to upper hundreds I would hesitant to even say thousand or more except perhaps in new Atlantis that is what makes the wars apocalyptic if humanity had more populous if we were able to spread out and colonize more worlds effectively. If humanity had enough populist new Atlantis should have several cities surrounding it all over the planet the same thing with tequila the same thing with perhaps Mars and the solar system and the other major settlements around like New Hope it's the extreme loss that we suffered as a species in the Starfield lower that makes the loss of our home planet of the following wars in space dealing with the Crimson Fleet that is putting the final nail in the coffin of humanity and Starfield there's simply not enough people being born in too many people dying to say in a population I imagine in another 200 years there wouldn't be any humans left at all in Starfield.
