“Throughout the history of theology…Christians have swung between the idea that Earth can be the only inhabited planet because God favors humans, and its counterpart, that to assume Earth is the only inhabited planet is the height of human pride because God is limitless and all-powerful.” So states a recent article from the Christian ministry SkyWatch TV that entertains the possibility of intelligent alien life in outer space that can be as intelligent as or more intelligent than humans on Earth.
There are a significant number of Christians who, like the ministry above, believe in the possibility that there are extraterrestrials out there somewhere. Many of them argue the Bible is not a book that answers every question, therefore it’s okay for us to believe and promote the idea of extraterrestrials. I am of the opinion that, based on what the word of God says, the only intelligent life out there is angelic, not physical, intelligent extraterrestrials who build spaceships or other technologies to explore other worlds.
My opinion is based on the following scriptures:
Genesis 1: This whole chapter is about the focus of Earth as the center of importance for all of God’s creation for the benefit of man and ultimately for his own glory. It even speaks of God creating the heavenly bodies for the benefit of life on Earth (Genesis 1:14-18), not life on other planets.
Romans 8:19-23: “For the earnest expectation of the creature waiteth for the manifestation of the sons of God.” So begins this passage. It speaks to how the fall of man in the Garden of Eden had a negative effect on all of God’s creation, including outer space. Every creature God created, including man, and everything God created (Romans 8:22) is groaning as they all anticipate the glorious redemptive manifestation of the sons of God–i.e. all believers in Christ. They’re not groaning in anticipation of the manifestation of super-powered aliens.
1 Corinthians 15:3; Galatians 1:4; 1 John 2:2: Jesus Christ came as God in the flesh to die exclusively for the sins of mankind. If there were other creatures out there like man, he would have to die for them also and the Bible would have made that clear, but it doesn’t because he didn’t.
Hebrews 9:11-12; 10:10: Jesus only died ONCE for all. If there were intelligent extraterrestrials out there, they would be sinners like us and Jesus would have to die on their worlds for them, which would violate scripture. Even if his death on Earth would have covered extraterrestrials, he would have commanded and made it possible immediately for the disciples to spread the gospel throughout the universe–he didn’t.
Ephesians 4:8-10: The Lord Jesus ascended to heaven after descending to the “lower parts of the earth” so he could take the captivity of sin, flesh, and the devil’s works captive in order to give gifts to “men,” not extraterrestrials. If there were intelligent aliens similar to humans or superior to them, would not the scriptures make it clear that they received his gifts also?
2 Peter 3:7-12; Revelation: Throughout scripture, prophecy warns that the heavens (outer space) and the Earth will be judged and destroyed by God because of mankind’s sins and the sins of fallen angels, not because of the sins of aliens. If aliens existed, they would also be sinners and God would be unfair to specifically target mankind and fallen angels without mentioning extraterrestrials also. We know God is without partiality, or favoritism (James 3:17).
These are just a few scriptures that have led me to believe aliens are the stuff best left to science fiction, not Biblical facts.
