I've been involved in the study of the UFO phenomenon at a very deep level for almost six decades. Some 48 years ago - after I'd been born again - I experienced a close-up UFO (a daylight disk at a range of about 50 yards, not some "unusual light" in the night sky) in the company of a guy who thought my religious beliefs and UFOs were both nonsense (until he saw the UFO). People I know and respect who have no interest in UFOs have reported experiences to me that were absolutely mind-blowing.
Despite my studies and experience, the UFO phenomenon has had essentially no effect on my religious beliefs. The speculation about UFOs possibly being demonic dates back at least to Rev. Barry Downing's 1968 book The Bible and Flying Saucers. Such speculation continues today. Nick Redfern, who is a pretty reputable thinker in this field, published a book in 2011 suggesting that a highly-placed "inner circle" with the U.S. government believes UFOs are demonic in origin (FINAL EVENTS and the Secret Government Group on Demonic UFOs and the Afterlife).
Some species of Christians are very quick to dismiss everything that challenges their beliefs as "demonic." Near Death Experiences are "demonic." UFOs are "demonic." After-Death Communications (of which I've experienced several that have greatly reinforced my religious beliefs) are "demonic." Reincarnation research is "demonic." Seldom do these folks have a deep understanding of the subjects they dismiss.
The UFO phenomenon is complex and multi-faceted. Very few in the field think in terms of "aliens from other star systems" anymore. "Demons flying around" doesn't come close to fitting the phenomenon (or more properly the "phenomena" since there is no single "UFO phenomenon"). The phenomenon definitely does have, however, a "psychic" or "spiritual" aspect.
My guess would be that the UFO phenomenon might be used by demonic forces to steer people away from the truth. All areas of "weirdness" such as this can easily become obsessions and even quasi-religions. Many researchers have warned against becoming too deeply involved. This is the sense in which I believe UFOs - and lots of other things, including Facebook and Twitter - might be demonic.
The Bible does not talk about how Christ will redeem... "worlds" (plural) and how all of them will live on the New Earth. Nor does it say if these other worlds will be condemned at the judgment, either. This is merely the influence of Science Fiction upon men's minds (and their love for it). But the Bible tells us not to love the things of this world (See: 1 John 2:15-17). Also, those who have encounters with aliens sometimes smell brimstone, just as those people who have ghost encounters sometimes smell brimstone. Brimstone is associated with hell in the Bible. That is just one coincidence. Another coincidence is that whenever somebody gets involved in the occult, they are more likely to have alien encounters or alien abductions. Another coincidence is that these aliens or UFO saucer phenomenon can be cast out in the name of Jesus Christ.
I remember one time, I watched a video by a Pastor who referred to how the word "owl" can sometimes refer to demons in the Bible. The Pastor said that the shape and color of the eyes of owls matches up with the shape and color of the eyes of the ever popular grey alien that people see when they have alien encounters (i.e. black almond shaped eyes). At the time, I didn't think much of it. But then months later, I seen a trailer for a movie called "The 4th Kind" and it was a movie about alien encounters. What was disturbing is that they showed owls in the trailer with them morphing into these grey aliens. In the trailer, it looked like these people were being possessed, too. Very disturbing movie trailer.
I used to be a huge fan of Star Trek, and Science Fiction. I collected the five major series of Star Trek (at the time) on DVD from the Original Series to Enterprise (and knew many of the episodes by name). I even went to Star Trek Experience in Las Vegas (When it existed) several times, and I had been to one Star Trek convention. I even played the role playing game with my ole buddies. But after seeing the many sinful things being pushed within movies these days, I put away general sinful secular movie watching, and I now only watch Christian movies, educational documentaries, and a few occasional wholesome good family value romance films (to watch with my wife).
Another problem I had with Star Trek is that it promoted Atheism and Evolution.
Granted, there were a few episodes and exceptions to this, but they were not common (Unless you consider DS9's storyline on the alien like gods being like of the Bible - of which I do not agree with). The creator of Star Trek (Gene Roddenberry), was strongly against Christianity and he even insulted God and the Bible.
Most of the time, people love to fantasize about aliens out of their love for Science Fiction. But most of your Science Fiction pushes sinful things within them. So while I am glad you may consider aliens and UFO encounters as a part of a demonic deception, it is my encouragement to all to get in the Bible more and ask God to show one the truth on this, and He will. I know for a fact that aliens are a part of one of the many demonic deceptions in these last days. So my encouragement to all here is: Don't fall for it. Get in the Bible more and put away either your love for Science Fiction and or your love for the fascination of UFO encounters.
People ask, then why did God create the universe so big if there is no life on it?
Because God is big and He does things big and magnificent.
For God has even named all the stars.
I hope this helps and may God bless you today.
