What happened to the dinosaurs? The prevailing theory for the extinction of dinosaurs involves an asteroid collision at Chicxulub in the Yucatan Peninsula of Mexico. Whether you accept that theory or not, there is no question that there are vast numbers of asteroids in space. They are apparently leftovers from the formation of the planets. At least nine times an asteroid has hit the earth leaving a crater that can be studied and mapped today. Some of the craters are huge. The largest is a crater 186 miles (300 km) wide in South Africa called the Vredefort crater. The question is, “Why would God allow such objects to exist knowing they could become a threat to life on Earth?”
First, we need to realize that such collisions are incredibly rare and so far they have never impacted humans. There are more than half-a-million known asteroids. The largest is Vesta (pictured) which is 329 miles (530 kilometers) in diameter. The smallest are only 33 feet (10 meters) in diameter. Objects smaller than that are called meteoroids. According to NASA, the total mass of every known asteroid is less than the mass of our Moon.
Scientists are studying their chemical composition of asteroids. What they have found is that they are very rich in rare-earth metals as well as iron, nickel, and cobalt. In the future, we may replace depleted resources on Earth by mining asteroids. Experts have estimated that the value of minerals in asteroids is in the trillions of dollars. Two American companies are gearing up to pioneer asteroid mining operations–Deep Space Industries and Planetary Resources.
We think too small when we think that God planned for humans to be limited by the resources of Earth. What appeared to be a threat in the past may turn out to be an incredible blessing from God in the future.
