If it is indeed a simulation, it could basically be a video game (or perhaps series of games with time-between-them last-thursdayed into our memories) and what video game that has a story has no conflict

If we are in one why build one "in-universe", sure you can make your Sims play The Sims but most people don't make them spend all their free time that way

Despite what movies like Interstellar might put into people's heads about colonization, if we fix Earth, we can occupy more than one planet at a time

I'm trying for a music career (and would likely be far along by the time we had the tech if you're not metaphorically asking if I'd go now) so I'd need some way (either with FTL communication or some sort of satellite daisy-chain) to have lag-free Internet on there and enough infrastructure that it could support things like a recording studio

Then why not just fight wars with a poll among both nations' people about who'd want to fight on the front line

how's it not a problem because it's natural

aka "I want the apocalypse to happen because I'll have plot armor because #aesthetic"

A. what does that say about our video games/the likelihood we might be in even a Variant of one of ours?

B. someone has to be in the real physical universe and anyone in a universe capable of coming up with this idea could make that claim equally validly

Are you saying that some people practicing celibacy means this would happen?

Why?

you're assuming it happened to them because it might happen to us and we don't see aliens

And also pollution doesn't mean pollution to the level we're doing it even if it were in the same form

If it's truly that direct a parallel between us and the bacteria, part of why god (if you're saying it's a separate entity and not following OP's logic which would also mean we were somehow the bacteria too) wouldn't intervene/would look like they wouldn't care is because they couldn't communicate with us in a way we'd understand and any physical intervention could just wipe all of us out not just the aggressors

FYI for all people in the comments talking about how some humans still don't have rights so this is bad, by your same logic slavery should have continued until all white men were equal and women only granted things like the vote and not being property once all men of all races were etc. etc,. Instead white women didn't have to wait for racial equality for suffrage to be a success
