For the 2-B stuff, im ignoring the extra fate hax point now since, again, that was just an extra proposal coming from this, so I don't care if it's not legit enough for fate manipulation.
Being able to time travel doesn't magically mean you're able to say it is a different timeline, Kukui. Again, this just seems plainly ignorant of how we determine things on the wiki. This isn't evidence, I shouldn't even have to explain to you that it isn't.
What says I can't? Time traveling directly indicates the world in question has different points of time. Past, present and future, aka it is a timeline. I fail to see how this isn't enough.
So if I copied the solar system, I'm copying the universe? Are you hearing yourself? Dude? There's shit outside Earth.
Where is "solar system" coming from? That is not what was said, or what I said. The point here is that these worlds replicate the real world. The real world in context can only refer to one of 2 things here as options. Our planet earth or the entire scope of the real world's reality. Aka, the universe. And this is the most common interpretation of "the real world" in fiction by far as well.
And as was explained multiple times already, the real world in the context of "just earth" objectively is not the case here, since these worlds demonstrate cosmic sizes beyond the scope of our planet. Stars were depicted in the very first commune shown to us, a commune also said to "be earth". Limiting it to the scope of just our planet doesn't work with this, so what interpretation is left to use when replicating our world beyond earth? Simply put, the universe.
And as said in the last thread, Hao creating a universe in a commune inside the Great Spirit further provides evidence of the communes being universe sized and replicating our world on such a level. And yes, Hao created a universe, as was determined and agreed on before (as Cyber above summed up).
So 2-B should very much still remain on the table here.
