Trying to imagine if nothing ever existed...
I mean, woah just woah. If nothing ever existed, we wouldn't be here. But if we weren't here, then we wouldn't be able to have any thoughts or experiences ever. And if we didn't have that, then we wouldn't be able to think of this very topic rn...
And the earth as we know it wouldn't be here, or the rest of the universe for that matter. And, speaking of matter, there wouldn't be any of that either.
So pretty much every single thought, experience, event, memory, and all that jazz would've never happened.
And it's not just what's in our minds. We ourselves wouldn't be here! And the entire world as a planet, and the other planets, and the stars, and all of the naturous things wouldn't be here. Let alone all of the things created by man...
(See, I would continue going on, but I think I'm rambling too much. XD)
