NASA reports that our solar system has "water, water, everywhere!" Not too long ago, we all thought that the earth was unique in this respect. However, in the last few months we have seen strong evidence that water exists on Mars, Europa, Enceladus and Ganymede. Moreover, we have learned that some of these orbs may host vast liquid oceans under their crusts.
Does water mean life? Not necessarily, but it does make life on them a possibility. What does that mean for God and us? If there is so much water within our own solar system, doesn't that suggest that other systems could also contain water? What if there are other worlds with living organisms? What if we're not alone?
I can't find any Scripture in the Bible that explicitly states that this planet hosts the only life in the universe. Could God have other children besides us? If "He" does, does that make you jealous? My guess is that it would make a lot of people very uncomfortable. Many of us have a hard time imagining God caring about any of the other organisms on this planet - let alone caring for any life outside of our world! If such organisms exist, would that diminish the importance of life on this planet? If intelligent life exists somewhere else in the universe, does that in any way negate or cheapen our status? Is God great enough to keep track of folks on other planets and provide for their spiritual salvation?
I believe that God is big enough to handle any life that might exist in the vast out there. I don't believe that there are any limits on God's capacity to create and sustain children wherever He/She/It decides to do so. And if we ever do find life out there (or those little green men show up on our doorstep), I can assure you that it won't shake my faith in God or cause me to reject Christianity. What about you?
