Wide spread assumption is that elites made some deal with aliens around 1970 and elites trying to fulfill their part of deal taking over planet and population.
What if things are completely opposite?
Shortly - more advanced aliens find out that humans are not developed enough for full-scale contact. However, elites have some knowledge of and may be contacts with aliens. Aliens told that it looks like Earth will be ready for contact in 21 century. IDK, some invention or some parameter of society development, or both, based on trends that was observed in science and society.
During that conversation with aliens elites made a good face, but after aliens departure they come to obvious conclusion, that joining of Earth into interstellar community will mean loss of higher power status for elites, as I wrote earlier. As soon as existence of any more developed aliens will be revealed it will immidiately mean that Earth elites are not highest power for humans and humans could flee from the elites control, and since space is endless, even if Earth elites somehow eventually reach you, you always could flee slightly further from them. But with high probability it would be just their complete and final fall.
So, they decided to stop scientific progress and do not allow social trends to develop freely to avoid passing alien's thresholds.
Take a look at diagrams at https://wtfhappenedin1971.com/ f.e. If pre-1970 trends would have been untouched, today we would live in completely different and significantly better world.
Same with science, continuing pre-1970 trend of growing number of fundamental inventions, that flying cars people dreamed about in 60s could have become already obsolete tech today.
Elites do not try to close the deal with aliens. They try to avoid creating conditions that could make that deal possible.
Presumably, elites know the date of next check meeting with aliens and trying to supress anything that could allow that deal.
That is why elites actions looks so illogical. They don't try to do something, they try to destroy as much as possible by any means.
Again, if elites had a deal with aliens to enslave humanity, their masters certainly would have provided some kind of textbook and assistance and highly probably nobody even noticed what is really happening, and their actions would not look chaotic and insane.
But if they just tryin to destroy all things aliens account as civilisation development, it would look exactly as it looks - imbecile trying to play wack-a-mole with population, destroying one thing or another, without any logic and plan.
And all that just to keep their status of highest power over humans and keep us under their total control.
Why come the nazis has ufos then? This theory is decent. But I think the alien invasion happened 25,000 years ago. Then the inhabitors created us humans as slaves.......then tried to flood us out because "they" were never supposed to create slave races, and break free will. Then Yaweh the alien tried to flood us to death where before that could happen a few brave explorers were told what was to come. And told how to survive. In the america region it was said aliens/insects took the native americans under ground.
Now these beings are inter/intra dimensional......and literally use us as batteries. Like monsters INC. They use our emotions as fuel. Fear, guilt, envy, greed, lust...are all especially "heavy" dense energies. Which is what these beings feed off of.
I believe the Aliens/demons/whatevers/xemxelves....taught some humans....maybe of their bloodlines? Watchers ring bells here? How to feed off of us....like Energy vampires.
Now we call them "elites" but they are just 2 knuckle deep in the ass queers.
The end. <3
Hardly. Invasion of the civilisation with ability of interstellar flights inevitably should leave something more advanced than stupid pyramides. There is no chance at all that this invaders leave no single trace of alloys, plastics, sophisticated parts manufactured from that materials and so on.
All that ancient shit that many try to pose as a proof of alien invasion looks like total shit compared to the traces that civilisation that could build interstellar ships should leave.
None of that stupid theories about ancient artifacts are logical at all. Humans get some advanced techology to cut the stones and used it to build just stupid pyramides. Not something that this technology will allow, but exactly what they will build at their low tech level. Seriosly, you got a magic technology to cut a stones like butter and move heavy things without much effort and you just build a fucking ugly pyramide? Tech does not work like that. If you have advaced tech, you use it to make advanced things. It's like using CNC laser cutter to cut simple planks and nothing more.
So, there are no evidence that there was any invasion with supplying advaced tech in ancient times. Some rare short visits - may be. Invasion with providing advanced tech to humans - no way.
When somebody tries to understand how this or that thing was done in ancient times, for some insane reason he take a look only on very narrow part of the problem and never try to think wider, even if that basic things about how technology really affect and interfere with society is literally everywhere.
I read nearly everything about that "aliens tech in ancient times" long ago. And there is always that inconsistency - presumable advaced tech used only to make coventional things and never to make advanced, out-of-time things. And nobody show any traces of materials and parts of that advanced technology itself. There are no chance that we found a lot of iron and even wooden things from that times, but not a single chrome-vanadium steel thing or titanium case or polymer part, etc. as remnants or traces of that alien advanced tech. Nothing at all. And none of the authors of all that books and videos never asked a very simple question - "Why?".
Depends on how you look at it.
Were the aliens dealing with this kind of situation and were like 'fuck it best we could do is get them to stack some blocks'
