There may be intelligent life on other planets but if so, the Bible doesn't mention it. If there is, it is because God put them there (just as He put us here), and their purpose is to glorify and serve God (just as ours is).
While it's interesting to speculate about life on other planets, it's important to remember that God is everywhere, and although our planet is very small, God has not forgotten us. He made us, and He provided for us by making the world so it would sustain life. Never forget the opening verses of the Bible: "In the beginning, God created the heavens and the earth. ... God saw all that he had made, and it was very good" (Genesis 1:1, 31).
But something happened to the perfect world that God created and that "something" was sin. Adam and Eve walked with God but in time they gave in to the temptations of Satan, and they turned their backs on God. And when they did, sin like a lethal cancer destroyed their fellowship with God and brought death to the human race.
But God did not abandon us! God loves us, and He was determined to bring us back to Himself. He did this by coming down to earth in the person of His Son, Jesus, who died so we could live. Do you know the God of the universe in a personal way? You can, by opening your heart to Jesus Christ today.
