In reality we don’t know really what sorts of powers angels are capable of exuding or forms that they can take on or if in their possession of humans, they can attempt to manipulate their hosts’ DNA.
Many so called UFO “abductees” report that their captors tended to be sneering and dismissive towards them, referring to them as “containers” as though they were empty vessels. (The import of that reference of being as ‘containers’ is of import when reading in the Bible of Jesus casting out devils.)
Some potential abductees report that these “captor”s tended not to like it when Jesus Christ is mentioned and spiritual songs are sung, even voicelessly and thus these folks, Christians of faith, are released abruptly!
I’ve long suspected “aliens” were actually demonic manifestations.
