We pointed out at the start of this article that there is no statement in the Bible which says that Earth is the only place where God saw fit to create life. The fact is that God has created angels and they are very different than are we, so we know that the creation of beings other than ourselves is a certainty, and the existence of other physical beings certainly has to be held out as a possibility. If life is discovered on Mars or on one of Jupiter's moons, it will have no biblical consequence. Religious people have made the mistake in the past of making something that has no biblical connection an issue. There were those at the start of the twentieth century that said man would never fly. These folks would use passages like
Acts 17:26 (KJV) which say "God has appointed the bounds of man and the limits of his habitation" to justify their view that man would never get off the ground. That might seem silly to us, but we need to understand that statements about life in space are of the same nature and have no biblical base.
The Bible addresses itself to man and to man's needs. When
John 3:16 tells about God's love, its object is man and that is who the message of the Bible is to. If there are other beings who are like us in any way, they may have a similar message that is for them. It is highly unlikely (given the distances that exist in space) that we will ever know if there is life out there, but even meeting a Mr. Spock or ET would not invalidate the Bible or the teachings of Jesus Christ or His sacrifice on the cross.
