And it's just a matter of time before any number of things happen. Just a matter of time before the Sun explodes. Just a matter of time before our galaxy and Andromeda collide. I suppose you could argue that we could all be wiped out tomrrow, but our sun won't die out for a few billion more years, which is true, but is there really any sense in worrying about it?

Perhaps I misread your post, but it sounds like you are saying that it's just a matter of time before we get wiped out so we shouldn't bother trying to stop the inevitable. But if we have the technology and knowledge to stop a potentially existence ending asteroid why not employ that measure?
