I don’t have the similarities on the top of my head . . . let me try . . .

—Jesus’ Name and Blood are effective against both.
—dabbling in occultic practices and materials opens one up to both.
—Evidently including, in some cases, horoscopes.
—Deception is wholesale in both.
—lies are common, the general rule, in both.
—half-truths and distortions are common in both.
—a clouded, diminished spiritual understanding and discernment is true in both . . . eventually resulting in a person unable to discern Biblical truth and more or less totally controlled by the dark forces in terms of construing reality.
. . .

Given those similarities, what I would expect is that is no physical manifestation of aliens is present, but rather that a spiritual attack due the occult practices has left the impression of a lie, that of alien abduction.

I could see demons using acceptance of aliens as a strategy to get people to reject biblical truth.

I'm curious, just how Jesus' name is effective against an alien abduction? How many people claim to have repelled aliens through the use of Jesus' name?

But I still really really doubt that demons are manifesting physically and abducting people, as opposed to manifesting spiritually.
