Disclaimer: It is a fictious theory with a possibility.
Not to claim it is the whole picture but aliens were involved in religions and languages historically. They have been watching the world possibly for entertainment purposes and they were also interacting.
One possible major interaction was around 1950. They contacted with US and let them capture one of their ships. They acted like they were come to realize life in the earth by coincidence and let US ambush their ships. Although this is very speculative even for this theory.
Recent comet named 3I/ATLAS was intentionally designed and send to make it look like an alien spaceraft from distance. And possibly synchronised with some other events to make it look like they were coming. Although I don't really have any idea. Recent gold rally and some other events indicates some global "elite" or governments did really think aliens were coming. Also even though many prominent people in US was trying to push cryptos. There was a weakness recently. Although it is possible they were just dumping it and paying US politicians and bureaucrats. But it is also a possibility that they think cryptos would be totally absolute under alien interference. Even so compared to fiat due to technical and other reasons. There is actually no reason to assume they would collapse governments and fiat currencies. Rather they would be taking over with soft power. This recent comet was probably specially designed to make it apperant that it was a comet after more visibility. So they did to fake it. To make a real surprise just after it.
I am expecting soon they will let us watch too. Well, maybe they will only let some people. Quran frequently mentions a time. It is possible that aliens were bound by religion to not interfere with earth until a time. Although it seems like they were interacting. Maybe it was more intricate limit. Or maybe there were directions given by God. I have been watching Lost. It kinda has similar theme.
If scope of watching is comprehensive, it is hard to comprehend how can they could be doing it without being noticed. But they may have technology that advanced beyond comprehension of us. For instance maybe they genetically engineered some mites or other life forms that lives on human flesh to form a mesh network. (Some Muslims even suggest covering sexual parts even when taking shower. Not a common practice, but originates from a common belief which is angels are watching. I am not saying angels similar to have imagined not watching but actually the term that used to refer to angels is very general term that also applies to aliens with superior technology. Even used as title for human rulers.) This would be extreme simplification but. There are so many biological phenomenas humans were not able to address even in the macro level. It is obviously not possible to comprehend limits of advancement in technology or whats possible even though the knowdledge we have make it seem like we should be able to imagine what is possible to very close to its limits.
It is also great possilibity that aliens were directly communicating or even commanding to some entities like top level government buroucrat in a limited and possibly not obvious ways. This is more likely in case the situation of aliens involvement were to become very apperant to some.
In Turkish there is phrase that actually literally means making a movie. “Film çevirmek”. It means what kind of play or conning you are doing when it is apperant there isn't actually a movie being filmed. Although it is probably very very modern addition. Still funny coincidence.
3I-Atlas may just be straightforward alien vehicle. Or maybe a space object modified by aliens. Maybe they send it intentionally to be visible an exciting to humans. Reputable scientists to my knowdledge, recently very popular figure in this topic, Avi Loeb was noting abnormalities and insisting on taking possibility of it is being an artificial object, more seriously. Well, I think there isn't really much humans can do other than continue acting :D
I was kinda sympathetic towards aliens since my childhood and I am actually quite biased. I don't really wanna believe aliens were watching and having fun. However they would be watching possibly centuries before they interfere with the earth because of many reasons. And actually without a religious bias there is no reason to think that they would care for sake of humans. How we don't interfere with wild animals. Though we can't even protect them against damage inflicted by us. We don't try to stop figthing animals or stop them from hunting each other. We actually eat them. There is no reason to assume animals are conscious but we don't really know. If consciousness is something measurable by aliens. It is possible that they may care. But otherwise like everybody else say just because we are intelligent, it doesn't mean much. It is also possible that aliens will be religious. That may also affect their behaviour.
In Quran the word for heaven and Jinn are the same. There isn't single word but at least there is one major word interpreated based on context. Which can mean heaven or Jinns. And this is actually nothing because In Quran it is frequently mentioned that God will cover or conceal whatever sin he wants. Which is ridiculous I mean from whom? Obviously even the traditional interpretation of Quran proposes a period very similar to what this complo theory suggests. Even if there isn't a alien invasion. If there are heaven and hell they are probably coming to the earth. And it will be for a period. Because return to the One as final clearly mentioned. Obviously current understanding confuses everything but those are very clearly and repeatedly mentioned in Quran according to traditional mainstream interpretation. Obviously because it is not very comprehensible there aren't much of a detail about returning to the One. There is a confusion about this. People imagine an eternal heaven. But return to the One as final explicitly mentioned.
The word Jinn actually most likely originates from Chinese. “Çin” in Turkish. And there is no “Ç” sound in Arabic. So “J” is closest. Obviously because at the times were Quran understood better. Whoever understood it, possibly the prophet, described aliens as creatures lives in very far away that are very similar to humans. So based on similarity they thought about China and later it stuck in the language. Also China was probably technologically advanced back then. An it was probably seen as mysterious because of limited accessibility. A better alternative to place like Rome for stories with “little” exeggeration upon return.
Quran is long text. And it is not really well understood at all to my understanding. It can be calimed that I am only mentioning things that fits to theory. Based on sentences over and then but I am trying to stick to fundamental concepts. And talking based on broad understanding that doesn't depend on any specific verse.
