Scientists aren't sure if it was a meteor or a pathogen that actually wiped out the dinosaurs, or a combination of both: pathogen reduced their numbers and made them too weak to survive in the harsh conditions immediately following the meteor. That's just conjecture, IMO.

What we do know is that there have been several extinction events on Earth and there is no guarantee that another is not on the way. Some surmise that every few hundred million years the Sun enters a galactic band of dust and gas that somehow causes havoc... and we're due for it again sometime.

The question is: where do we go and how do we live there when we get there?
