I don't necessarily agree with giraffe_lady, but I can see the argument where leaving the planet fundamentally changes what we currently consider "human" society to a point where it no longer can be a considered a continuation of the general earthly society. Evolution maybe, but less star trek and more belters from the expanse but taken to an absolutely extreme extent. Maybe closer to something like Seven Eves.
