Then you’ve missed the entire point of the original saying. It insinuates humanity will be extinct but some little rodent will survive. Or a lizard, or insects, etc.

Humanity is too good for anything the earth will ever throw at it short of a supervolcano. Extrasolar threats are about the closest thing that could take us out and we are A-OK as far as radiation bursts from nearby exploding stars go. That just leaves asteroids large enough to turn the entire crust into molten rock. In which case all life except potentially the tiniest deep in the crust or reintroduced through contaminated space materials will survive.

Humanity will survive the rest. Us poors might not, but humanity will lol.
