Is Satan is prince of the air / sky?
Ephesians 2:2
Following which you once walked, following the course of this world, following mthe prince of the power of the air, the spirit that is now at work in the sons of disobedience.
Satan is called the god of this world by St. Paul (2 Cor 4:4). The end of the world refers to the end of his reign and the beginning of Christ’s. But the Bible doesn’t talk about UFO’s in the modern sense. No sightings of shiny flying discs are recorded there, despite the broad interpretations by some.
