The Alien theory is very popular. Why is this very popular? Nobody knows but some people have some ideas about it. Some people say “We are not alone in this universe.” On the other hand some people think they are advanced civilizations and try to send messages to us. In the end they may be true.
The people are talking about aliens too much because they think we are not alone in this universe. These days we get signals from out of the world. This shows us they are alive and they know us and they know outside there is a live form. If we get this signal the experts did not find the meaning they only found the “WOW” word. This shows us they are advanced civilizations…
They are advanced civilizations because if they know the other galaxy or universe they will know everything about our universe and this will affect their future. This future is like if they know other planets’ civilizations they take inspiration from there. If they take inspiration from different planets they know everything and they think they can do everything. They took inspiration from every universe and they will increase their technology. Therefore they can travel everywhere in the universe, maybe to other universes…
Extraterrestrial life is life whose origin is not Earth. Although there are currently hypotheses that there may be life in the form of simple bacteria outside of Earth, there is no observable extraterrestrial life to date. But if this is real it will be hard to believe and people will be scared about it.
