Is it true that a gigantic meteor could hit the Earth and destroy all life?
Yes. In fact, scientists tell us that’s probably happened to the Earth once or twice in the past 4 billion years or so. Most recently, about 65 million years ago, a ten mile meteor may have struck the Earth and ultimately caused the extinction of the dinosaurs. The large meteor crater in Arizona is proof positive that “large” meteors strike us regularly—on the astronomical time scale. While these things are possible, I wouldn’t waste any time worrying about it. The chances of it happening in your lifetime are so remote you’d be better off making plans to eat healthy foods, exercise, and take care of yourself as though you planned on living to 100.
