For we do not wrestle against flesh and blood, but against the rulers, against the authorities, against the cosmic powers over this present darkness, against the spiritual forces of evil in the heavenly places.
Ephesians 6:12 Bible Gateway
Given that the universe is only a few thousand years old, which you may not accept but at least assume for the sake of argument, there is not enough time for an extraterrestrial civilization to build a space ship and brave the dangers of interstellar space to reach Earth. Before we might have been worried about nearby inhabitants of Mars or Venus, but I doubt anyone today thinks there is life of any sort on those planets.
Indeed, the only reason we thought in the past that such civilizations might exist at all was due to a belief in the myth of evolution over deep time. However, there is no mechanism for evolution. Genetic entropy put an end to the speculation that mutations filtered by natural selection over a lot of time and with a lot of luck could pop out life without God’s creative power. Mutations lead to extinction not evolution.
So, assuming the age of the universe is only a few thousand years and recognizing that evolution has no known way to occur, we do not have to worry about these material aliens from other planets nor any star wars scenarios with them.
That leaves spiritual aliens such as angels or demons. Indeed, there is evidence from the Bible (see Ephesians 6 quoted above) that we do “wrestle” with these “spiritual forces of evil”.
Ian Juby fills in some of the details in his four-part series on UFOs and aliens.
We should not forget that from a different perspective we ourselves are aliens, that is, foreigners, exiles, sojourners, strangers, or pilgrims in this world (1 Peter 2:11). From that perspective we should be storing treasures in heaven, our true home, not here (Matthew 6:20).

Very well said brother. The bible is clear who we are wrestling against. I learn a lot from your Sunday Walk. Keep them coming.
Blessings.

Hope you give us highlights from your videos. I am not a good video learner. Three minutes in and I am asleep. 😀 I do enjoy reading your conclusions “on the matter.”

I skip most of the videos myself when I read posts. They are there for those who want someone with more authority than I have. Most of what I know is what I said. Thank you, Oneta!

Some seem to want to forget some science: entropy, for example.

Good point about entropy. We tend to want to forget how entropy undermines many naturalist explanations of how things came to be the way they are. Thank you, Dora!
