That ALL life will go extinct is hard to imagine, but many scientists do see a high chance that humanity is going extinct (due to climate collapse) or, at the very least a population collapse of >95% is certain to happen within 200 years.
Civilization collapse in 200 years is pretty plausible, which would go along with 95% of the population dying. For humans to go extinct would take better than 99.9% dying. 5,000 individuals would be a comfortable minimum viable population for humans to survive.
Yeah, if they were in one place. Not 5000 remaining survivors scattered all sround the world. Also, keep in mind that this would be an ongoing catastrophe, not something the world will just bounce back from once the humans are gone.
