There are many things that could destroy the earth or at least civilization as we know it. There are asteroids, nuclear weapons, plagues, wars, volcanoes, atmospheric destabilization and massive economic collapse. Spend you time on this earth living, laughing and loving, because you can't control tomorrow. Stand always for what is right and just, and let God handle the rest. A person, or country, can be prudent and as prepared as possible for disasters, but so much of fate is beyond our knowing./p>
You are correct. We could get toasted by some blast of cosmic radiation that makes asteroids look like video game by comparison. Could happen today.
