The mystery of the disappearance of people across the planet is still controversial. There are three main versions.
1. Extraterrestrial civilizations
Scientists cannot but acknowledge the fact that we know nothing about the origin of our life. Who are we? Where are we from? Who created us?
There are theories, but none of them has reliable confirmation. Many scientists are seriously inclined to think that our planet was not just formed in outer space. It has ideal living conditions. Day and night. We were probably created by extraterrestrial civilizations. And they periodically visit the earth to see the fruits of their labor. The disappearance of people is their work. Not all, of course. But there are many.
2. Time loop
Promotional video:
A very interesting and promising hypothesis. People often experience the slow time effect. They go to the mountains for an hour, and when they return, it turns out that they have been absent for 5-6 hours. It is possible that some of the disappearances are related to this effect.
Temporary portals throw people back into the past or future. And this is a plausible theory. Scientists believe that time does not exist. All events that have ever happened on earth are happening right now. This is confirmed by the fact that people can see the future. Diviners. Wanga, Nostradamus. The future already exists. And so it can be seen.
3. Accidents
The most mundane version. Many people believe that there is nothing mysterious about the disappearances of people.
Accidents just happen. People fall into the water and stay there. Also, wild beasts may well destroy human footprints. Many people believe that there is simply no mysticism.
