Thank you very much for your comment! I agree with your comment on the human extinction risks that 99% is probably not high enough to cause extinction. I think I wanted to provide examples of human extinction event, but should have been more careful on the exact values and situations I described.
On re-evolution after an asteroid impact, my understanding is that although species such as humans eventually evolved after the impact, had humanity existed at the time of the impact it would not have survived as nearly all land mammals over 25kg went extinct. So on biology alone humans would be unlikely to survive the impact. However I agree our technology could massively alter the probability in our favour.
I hope that if the probabilities of human extinction from both events are lower, my comment on the importance of the effect on other species still holds.
