Kind of ironic to think that humans survived a million-year ice age, then might be destroyed by some fool with a button.

If 'our universe' is 'tuned for life', it certainly isn't specifically tuned for human life (e.g. plague, volcanos). Nature offers us no guarantees. Unless we stay in tune with that accord, we will be removed.

Aren't homo sapiens here only because an asteroid strike around 70 million years ago caused a culling that killed the dinosaurs and sort of reset life to favor small mammals over the dinosaurs? If perhaps that had not hit the earth, we would not be here and something that evolved from dinosaurs would be the top of the food chain and typing comments here! We had to get that one strike in at the right time (from our perspective) and then not another semi-apocalyptic event to get to here.
