They are demons, fallen angels. Typically, they mimic current technology--a century ago they appeared as zeppelins. There are two books which serve as the definitive works on this subject:
* The Bible carefully and frequently documents angels' innate ability to manifest themselves at will in any form in our world.
* Lights in the Sky and Little Green Men: A Rational Christian Look at UFOs and Extraterrestrials. Its main author, astrophysicist Dr. Hugh Ross, has studied UFOs and rUFOs for nearly 60 years.
I don’t think they are demons. I wasn’t going to speculate, but I can’t help myself. Apparently (and this part I don’t know first hand) they escorted Apollo 13 safely home. There is no evidence at all that “they” are hostile. I put they in quotes because those things could be drones. No idea. But nothing I’ve seen or heard indicates ANY hostile intent. Heck, based on lore (again, not first hand info) they have deactivated nukes. Perhaps they are protecting us from ourselves. Note that there have been no accidental launches nor have nuclear weapons been used since WW II. Are we really that good? Are we really that lucky?
+1 and they materialize or de-materialize right in front of eyewitnesses eyes.
Same with Bigfoot/Sasquatch (who are probably some form of Nephilim), demons/ghosts, ‘aliens’, and anything else in the realm of the paranormal.
They all come from the same source.
Evil = Demonic = Satanic
Every single eyewitness to these beings has the same petrified fear factor “paralysis” so to speak. Most are NOT Christian, so the religious factor can be tossed out there as well.
Interestingly enough, those who do practice the dark arts are almost 100% of all cases of ‘abduction’.
Ignoring the spiritual aspect of this topic is like not being able to distinguish the forest from the trees.
“In short, they are real yet not physical.”
The only thing wrong with that line is that it cannot be subjected to any kind of proof.
Also, the government is said by employees who was once worked in the related government departments to have alien crafts or parts of alien crafts.
They break the KNOWN laws of physics.
But as Bob Lazar explained it- they warp space/time around themselves and effectively pull themselves into a new space.
They do not feel a 90-degree turn. To them, they feel like they are standing still, and space is moving around them.
