If the so-called aliens are actually demons, how can we identify them as such? If we ask them about Jesus, won't they just lie?
A human is body, soul (behavior mechanism of mind will and emotion), and spirit. The body is luimited to the four D dimensional variables of the greater Universe. The spirit is not so limited and exists in greater dimensional variables realm as a 'spirit body', according to Paul's writing (if there is a physical body there is a spirit body').
An angel has a physical body in that greater variables realm, as evidenced by Bible passages such as Daniel chapter five. There is coming a day when those in Christ will be transformed int he twinkling of an eye, to have a physical body in the greater variables realm, a physical body fit to live in eternally. At some time in the future, after the tribulation and the thousand year kingdom, all the rest of the descendants from Adam will be resurrected into bodies that will exist 'unending' but those bodies will be sorted and too many sent to eternal damnation, physically alive but in torment.
When Jesus came out of the grave He ended the curse of deadness that followed Adam's rebellion to God. Thus all of Adam's descendants will have physical bodies that will not die, BUT the Rapture members of the Body of Christ are -after Jesus first- the first fruits of the resurrection. An ominous day will come when the rest of huamnkind will be osrted to go into eternity with the first fruits or into the fate of satan and his 'denying' minions.
How does that relate to the occupants of UFOs? Well, my guess is the 'little greys' and other manifestatiions are biological constructs limited physically to this 4D realm. But they have a behavior mechanism which may be 'engineered' by the fallen angels to have limits to their will and emotions and even their mental (mind) capacity ... they are biological drones, perhaps inhabited by demons, disembodied spirits given a drone to inhabit.
Once again, I will try to be brief, even though it’s not possible. 🤪 As far as demons lying, I couldn’t give you a definitive answer.
Let me say this. My wife and mother in law, were from Batangas. My MIL always used to say, you better watch out, or you will get pinched by a dwarf. I just assumed it was typical superstition. One day, the two were watching TFC. I wasn’t really paying attention, since I don’t speak their language anyway. At the end, in perfect English, they always answered questions people might have. Once, they said, what does it mean to be pinched by a dwarf? That brought me to instant attention. I don’t remember what they said, but they had video of it. I figured it out, in about 3 seconds. These were not dwarfs. They were little children, and were demon possessed. You could see it in their faces. It was grotesque, and ugly, with a capital U. I don’t know if all demon possessed people act like these children did, but some surely do.
It seems to me, that demonic activity, like this, is somewhat common in the remote mountainous areas. I have been there, and sometimes (not always) I felt like there was an oppressive presence, close by. I honestly felt like I was in the presence of evil.
