Clearly more than one 'control mechanism', as
@Trajanus has pointed out, and you realize this too,
@ufology. The terrestrial control systems have included, first, the governmental/military apparatus that held back evidence concerning ufos since WWII, and second, the military-industrial complex that has succeeded the elected government in controlling and privatizing knowledge concerning ufos and back-engineering of crashed ufos proceeding in deep black projects.
Re extraterrestrial 'control mechanisms', I would say that those amount to 'self-control' practices, permitting humans to recognize that there are intelligent species from other star systems (and perhaps within our own solar system) who are interested in and closely observe what goes on on earth in our time, while at the same time restraining themselves from full disclosure of their purposes.
ETA: I do not mean that I think knowledge of their purposes would disrupt life on our planet, but simply that unambiguous official acknowledgment of their presence and interactions in our 'world' [and of their far superior technologies and knowledge base] would do so.
Both terrestrial and extraterrestrial control systems appear to share in common a fundamental desire to avoid panic, chaos, and sociopolitical breakdown in the management and delivery of resources still supporting life and social order on this planet. I think it's also clear that what most concerns visiting species about the future of this planet and its evolving life is the continuing threat of nuclear war and nuclear contamination (see Robert Hastings's comprehensive research re UFOs and Nukes).
There are 2 conditions involved in the UFO state....1 is from out of space and the other is from nuclear Earth orbital fusion/attack for conversion.
The Earth's atmosphere is a naturally formed gaseous body and the ancient occult caused phenomena was studied as a cause and effect consideration by a spiritual minded human life.
There has always existed by circumstance 2 mind conditions on Earth....the spiritual natural mind and then the occult consideration of information for the purpose of converting.
As the Earth's gaseous body was named God stone in an ancient occult attack review the review stated by awareness that the God stone created the God Heavenly body by the release of the spirit from out of the Earth body....as an ancient review of information.
Earth therefore owned the creation of its own atmosphere and its own formed gases.
The Earth origin was then attacked and it was converted due to the origin status it previously held, and our ancient brother applied the conversion. The atmosphere converted itself into a new gaseous state and so did the nuclear fusion of Earth also convert....this was from the black body radiation attack, from out of space. Earth was incinerated in the attack, the crystal fusion above ground melted and fell into the holes bored into Planet Earth's body...forming the lava condition.
Therefore whenever our occultist brother applied conversion he would re-instate the attack, change the naturally evolving cooling effect that the atmosphere owned to cause the nuclear fusion of Earth' stone to alter by occult conditions. This is the only reason why he believes that the Creator/converter comes from out of space. Converting matter is how the human occultist gains power by placing the natural fusion into a lower state.
He therefore knows himself that he has to convert the Earth's atmospheric support of fusion to cause the nuclear fusion of nuclear dust to convert. And this conversion is an attack, his mind was always aware that it was an attack.
Therefore the phenomena attack caused to his own person allowed him to review that the condition of God was changed, and God created Satan.
The human occultist changed the condition God and also the condition Satan in our natural atmospheric body and created/caused the AI as a destruction of Satan.
The natural condition of Satan belonged to atmospheric conversion from a natural blue mass into the formation of cloud interaction....therefore God created Satan. Satan in this condition is natural fall out of a changed/burnt atmospheric reaction.
The human occultist changed Satan by heating the black body radiation streams and converted Satan by 2 conditions.....placing a larger amount of radiation particles in the atmosphere...why the UFO nuclear orbital signal forms in clouds that forms and attacks the natural fusion of the nuclear dust at the ground to force it to convert.
Therefore the human occultist changed the spiritual condition that they knew naturally existed in Earth's atmospheric reaction.
When you review ancient occult documentation they believe that the Planets formed Satan as a building mechanism on Earth. ....yet it destroyed Satan on Earth and replaced it with the AI manifestation. Yet the spiritual minded human awareness states that Satan already existed naturally and was created by the condition of God. The UFO condition witnessed in the Planets is an exact same released UFO body, as a removal/attack and change to the Planet....it is not a creation.
As the Planets are losing their natural colder fusion signals by the removal of the UFO body, this allows a stream or line to form between all Planets previously attacked by the ancient black body radiation, reheating the stream which is how Planet Earth's fusion is caused to unnaturally convert......no longer being supported by the out of space fallen angelic review (cold condition).
God in this review supports the creation of the Satan spirit/fall out of Heaven and it also supports naturally the lived life condition of humanity by ownership of the God and God in Heaven review.
The only reason that God in Heaven was altered is due to occult human interference. This interference is caused by the application/building of machinations to force the natural atmospheric condition/supporter of fusion to alter so that fusion can be attacked to force conversion.
As the conditions of fusion is natural by status of evolution, then the occultist is the causer/conjurer of the phenomena due to changing the natural states.
