Did God create life on other planets?
The Bible teaches that the Earth is the only place in God’s creation where life exists since all things in the universe were created specifically for man. All other celestial bodies besides Earth are merely adornment of man. Genesis tells us:
Notice the three reasons the Lord made all celestial bodies in the universe: signs, seasons and days and years. Pastor Armstrong explains these reasons in detail in his Genesis study, but in summary all three reasons point to man. They exist to provide use for God in communicating to mankind. These objects have no purpose outside of man on Earth.
Beyond the reasons given in Genesis 1, the Bible says the universe testifies to man concerning to the glory of God:
Here again, the Bible states that the heavenly testimony is a declaration for man’s sake. The universe is for man. Next, the Bible says that man rules over all that God has made:
Man rules over all (not just some) of the works of God’s hands, which precludes the possibility of other life existing outside of Earth.
Finally, once the Lord returns to Earth and reigns in HIs kingdom, then the entire universe is destroyed according to scripture:
Likewise, Peter declares that when God's program for earth reaches conclusion, God will destroy the His first Universe:
The fact that our universe’s end will come once God’s program of events on Earth has been completed tells us that there is no other program taking place simultaneously elsewhere in the universe. The events on Earth dictate the beginning and end of everything in the universe. Clearly, the Lord made the universe for us, and therefore the rest of the universe must be lifeless and without a plan of its own apart from Earth.
Knowing that Earth life is alone in the universe, then we must conclude that the reports of “aliens” and spacecraft are either hoaxes, mistakes or demonic appearances. The demon world is capable of manifesting in various ways, and it seems reasonable to assume that demons make such manifestations from time to time to provoke fear and unbiblical speculation among the people on the earth. Such speculation serves to undermine confidence in the word of God, which is a priority for Satan and his armies.
Nevertheless, careful attention to the word of God alone will lead us to understand that there is no other life in the Heavens beyond what God created on this planet. Mankind is unique as God intended, and maintaining that understanding will serve to magnify our love for God and awe of His works. We alone were made in His image, and we alone have been provided with a plan of redemption through Jesus Christ (see Heb 2:16).
