Why do humans think that we'll live long enough to experience the world ending. We may experience our species end before the world.

Our world will end when our species dies out. The world we know and are familiar with. The earth will be here long after we are gone.

I don't think anybody, really, thinks that (as a definite). That's just a thing "pseudo-intellectuals" throw around, when someone says for example "When do you think the world is going to end?"

Instead of addressing the question, they throw into a fit about how they're only one intelligent enough to see that the world isn't going to end, just humans are going to mysteriously disappear, perhaps due to another Biblical flood or something.

This, although there are several legitimate scenarios for the Universe to come to an end, countless for different definitions and colloquialisms of "the world", and no practical reason to think that sentience MUST come to end as long as the Universe is capable of supporting it.

Or, they might just be meaning it as, you know, a hypothetical. But people are also perfectly comfortable using it as shorthand for the usual "end of the world as we know it".

The world ends for us when we die.
Most humans know they will die but don't truly believe it. We think we have tomorrow.

Good question . 👍️

That's why they carefully choose with which party to cast their vote!

I don't think that

That would be crazy.

Depends on what faction will win the war. Humans don't surrender that easily.

Probably because it's more likely that we will destroy it before some outside force does
