In recent years people thinks there are extra-terrastrials creatures and advenced civilizations. I agree with those people who think there are extra-terrestrials creatures like aliens. Actually there are some evidances about extra-terrastrials creatures. For instance people took photos of unidentified flying object which is called ufo. While this evidence is influential in my belief against aliens or extraterrestrials, that is not the main reason why I believe in aliens or extraterrestrials.
The real reason that makes me believe in extraterrestrials is that the universe is so big that it surprises me so much. Let me share some information, that surprises when i heard, with you. I will explain these informations as numerical data so you can easily understand how universe is big. There are 2 trillion galaxies within our observable Universe. In addition there are 1025 planets that orbit stars, with some addition pf the starless planets that number increases 1026-1030. The reason I’m explaining all this stuff is to make us think about how we can be alone in such a big universe. I think this is an impossible possibility. There are definitely non-human beings in this universe outside of us. I am inclined to believe there are extraterrestrials even in the galaxy we are in right now.
The photos and videos about extraterrestrials that taken by some people which i mention above. So these photos and videos show us that aliens may have visited Earth, but these videos and photos may not be real. In other words, if we consider the existence of aliens according to the size of the universe, I can definitely say that they exist, but if we look at these photos and videos, I cannot say for sure that they exist.
As a result, I think that aliens, that is, extraterrestrial beings, exist, but the size of the universe proves this to me definitively and reliably. Of course, among all the planets, there are advenced civilizations like the Earth. We need to do more research on this.
