The definition of an “extraterrestrial” is something originating, existing, or occurring outside the earth or its atmosphere. According to the Bible, there are “extraterrestrials,” however, it may not be the ones you are thinking of.
The Bible says that God’s angels live in heaven (Matthew 22:30) and go to and from heaven and earth (Genesis 28:12). Therefore, His angels are technically “extraterrestrials.” However, they are not like the extraterrestrials, or aliens, that are seen in movies.
Also, the Bible says that there are sons of God that sang at the creation of our world (Job 38:7). However, a son of God is anyone who is led by His Spirit (Romans 8:14). Some have argued that these sons of God could be beings in other worlds, but they could also just be angels of God. We will have to find out when we go to heaven one day.
The extraterrestrials or aliens in movies are often portrayed as attacking or endangering our world. However, the Bible teaches that there is only one “extraterrestrial” that we should be concerned about. This being is Satan who was once a glorious angel that dwelt in heaven (Revelation 12:7-9). He was cast to the earth because our world accepted him as our prince when we chose to sin (John 12:31, Genesis 3:4-6, Romans 6:16). When Satan was cast out of heaven he was confined to our world until his final destruction. John wrote, “Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time” (Revelation 12:12).
The good news is that Satan and all those who are on his side will be destroyed at the end of time during the final judgement (Revelation 20:10, 15). This is why we must put our faith in the ultimate “extraterrestrial” Jesus Christ who came down from heaven to save our sinful world (John 6:42, Matthew 1:21). “This is a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief” (1 Timothy 1:15).
