Ever since mankind are discovering the universe, there always had been theories and arguments about different topics in universe.One of the most known discussion is whether aliens exist or not. Some people say that Earth is the only planet inhabited by the living organisms . And some say that we are obviously not alone in the whole universe because it is endless. There is also quite evidence to think that there are other living creature beyond the Earth.
My opinion about this topic is believing that there are aliens that we don’t know about. First of all, the universe is bigger that what we think it is. Let alone other galaxies there could be even another universes. So it would be unfair and selfish to think that we are the only ones living in our universe. There is no evidence proving that we are the only ones existing, so why would we think that we are alone in this huge universe. The light waves from remote galaxies comes from a very long time ago, some of them even didn’t reached out to us yet. Therefore it means that maybe other creatures from other planets tried to reach to us but we just didn’t receive their message yet, due to how late they come. There is also evidence-like sources that we know coming from ancient times. For example there is painting created in the 15th century , it shows the Virgin Mary and in the backdrop of the painting, a man and his dog staring up at a hovering disk-like object that is suspiciously familiar. Looking back to these paintings , a lot of people thought that it was a UFO and took this painting as a evidence. I bet you know that the theory about aliens building up the pyramids of Egypt, since it would be really hard to create very advanced buildings at that time. That is why people are assuming that aliens built them.
Even though for some people these things I said may not sound like a
believable source, as far as I’m concerned it would be better to assuming aliens existing rather than thinking we are alone in this huge universe.
