UFOs as Spiritual Deception: The Christian Demonic Hypothesis and W.V. Grant Sr.'s 1954 Booklet
To the point
Some Christians interpret UFOs as demonic or inter-dimensional deceptions intended to undermine faith, a view popularized by Walter Vinson "W.V." Grant Sr. in 1954 that ties sightings to demonic disturbances and messages opposing biblical teaching, and echoes the belief that Satan can masquerade as an angel of light to counterfeit a gospel of cosmic evolution.
