If all of the Primordials, the Incarnae, the other gods and the Exalted host worked together on a project to do so, they could have easily sorted things out without violence, and with everyone happy.
They could still do so today, it'd just take a bit longer.
Of course, if all of humanity worked together, we could solve most of our problems too. No war, much less disease, hunger or poverty etc.
It's just not going to happen because we're diverse enough that we can't agree on common goals, don't have the means to fairly administer any such effort and our stupid emotions get in the way.
So yes, you could probably build Creation 2.0 somewhere in the Wyld. Get enough Solars with Wyld-Shaping Technique, get the Maidens and Sidereals for Fate 2.0, have the Lunars and Dragonbloods defend it while you build it, get all humans there via wyld-proof artifact vessels, create beautiful sanctums for the gods, establish a fair system of prayer, use Adamant-circle sorcerous workings to make everyone immortal. There you go, utopian post-scarcity society full of immortals. Leave Creation to the freed Yozi, probably keeping the Underworld in check too.
Yeah, except that'll never happen. The Yozi are too mad and too narrow-minded to agree to that. Nobody could coordinate the Exalted host like that. Eventually, someone with enough power would be unhappy with his lot and upset the whole thing. Or the Yozi have justified paranoia against the Exalted host, or the host against the Yozi. Or the Solars against the Sidereals, or the Dragonbloods against the Solars. Etc. etc.
None of the actors in Exalted are perfect (not even the Unconquered Sun). Any solution that would require perfection will fail.
(Assuming such a thing is even theoretically possible in your version of the game, which might not be the case.)
