Christian author and filmmaker Derrick Warfel argues that ghosts are not the spirits of deceased people but deceptive supernatural beings. In an interview with The Christian Post, he described ghosts as 'deceiving evil spirits or demons', explaining his interpretation of biblical teachings about death and the afterlife.
Warfel's position forms part of a broader argument in his book, UFOs and God: Revealing Deception and Truth Behind the Supernatural, Invisible War. He contends that UFO encounters involve fallen supernatural powers rather than extraterrestrial beings. The book connects this argument to Ephesians 6:12, a biblical passage concerning spiritual forces.
