They are preparing to blame a seemingly catastrophic event (possibly the Rapture) on UFO aliens. Satan will need for the world to not understand the event as proof of God, and Satan’s demons will be there to help. ???????
Makes sense.
2 Thessalonians 2:11-12 King James Version (KJV)
And for this cause God shall send them strong delusion, that they should believe a lie: that they all might be damned who believed not the truth, but had pleasure in unrighteousness.
