A belief reinforced by aliens at global scale. But U.S. specifically heavily trolled by aliens. It is without any doubt clear that U.S. government had severe alien phobia and they did probalby even fund movies that demonize aliens. At first purpose may look vauge. But it is because they fear if people believe aliens exists it will become real. Like self-fullfilling prophecy. Core ideology is extremely common regardless of what you think because most people are not open about it but they possess some level of similar belief. Origin of this belief is I suppose mostly aliens.
Alien phobia can also be observed on various governments. Especially European countries, Russia. This observation is not over disliking about existence of aliens. It is directly on emphasization attemps of aliens are kid fantasy. Many thinks there are aliens or it is very likely but somehow they also think it is matter of belief. I suppose it is because aliens wanted them to coconspire against existence of aliens on purpose. And obviously it may be necessary for governments to not leak any information regarding aliens. It is also possible some Muslim and Jews also collectively share similar ideas and coconspire. But in their case it is not about aliens or aliens not part of their conspiracies. It almost seems like British put great deal effort to not look like only fool of the Rome.
I am pretty sure there are countless different ridiculous beliefs in Turkey. Even without alien influence. Or they do some interactions and let the rest to imagination of people. Without surprises it wouldn't make a movie for aliens. Otherwise I guess they would have ended it by now. Although there are no gurantees that there is some sort of end. It is not possible to know what kind of purpose or agenda they may have.
Throughout the history aliens realized many belief of humans potantially originally originating from themselves. In many occurences those may be claimed as miracle. But obviously in existence of aliens you cannot know.
It is possible that there are people who won't even believe when aliens come and say it was them. There will be still people who will think it turned out as such because people believed so. I think they consider it somewhat collective phenomena. But not necessarily depending on the view.
There may be many reasons besides trolling and filming humans. I think they especially deceive high profile governing people so things can stay secret. Secrecy surrounding a lot of things is very suspicious although it may mostly come down to ignorance and heritage.
Not that I think interpretation matches the underlying text but some of the things here may be familiar to Quran readers. Although nothing precise just taking not of it. Nothing precise but talking about things that are repated over and over again.
