The Yellowstone Caldera erupting would probably do it, too. Also, a sufficiently big meteor, a rogue planet, or black hole. All would are beyond our current level of technology to survive or avoid. Or a local supernova, although there are no known likely candidates so that one is less likely.
Technically the cosmos are moving in such a way that our entire galaxy could collide with another celestial body at any moment if it were moving at sufficient speed relative to us, and we might never see it coming because the speed of light is only so fast.
This, and space is huge, it’s really unlikely to get hit by anything. It will happen over infinite tescales, but I’m not as worried about it as I’m worried over another work email.

With meteors it isn’t if, it’s when. The question is whether or not we’ll be ready for it when it happens.
We’ll let it hit us as 2 superpowers argue and threaten one another over who gets the mineral extraction rights.
I guarantee it.
