If I left out any, feel free to add.
1 and 3 are extremely unlikely to result in our extinction.
2 could definitely cause us to go extinct IF we don't manage to become a properly
space faring species before it happens. However the probability of an impact large
enough to wipe us out is very very unlikely in any given century.
4 is possible, but unlikely, even with nukes you have to go some to actually make
5 Humans will not last this long, that's not to say that our descendants might not still
exist, but they wont be biological humans any more... And will not have been for billions
6 not going to wipe us out [or even necessarily be bad].
7 [virus] certainly possible, but getting less likely as our medicine gets better.
8 [Supernova] possible but no star capable of going nova will be in range over the
next 100,000~1,000,000 years or so.
9 Depending on how you define 'human life' my response would be evolution/transhumanism
which will slowly or rapidly change us over time/generations to no longer be humans as we
define them today.
