Abstract

With the development of technology and the input of the space exploration, human know more and more about the earth, the solar system, the Milky Way system and the universe. At the same time, people are more curious about the existence of aliens. Do they exist? How`s they look like? Where are they? However, no one can really give the convincing answer. But we can have more possibility to believe which one is more convincing if we compare what we have found. And in this paper, to judge whether the aliens exist or not, I research many papers and read the argument from some famous scientists, and then I show three different supporting point of the both sides. And finally, after the three comparisons, I think we have more possibility to believe that the aliens do not exist. And I hope people who have the same ideas as I do can provide more convincing evidence to support me and I do welcome the convincing evidence of the opposite point.

Introduction

The world is advancing. The society is going ahead. The technology is developing. The space exploration is increasing. Human have more understanding about the earth, the solar system, the Milky way system and the universe. In this process, human begin to be curious about the existence of the aliens. Is there any other life in the space? Do the aliens look like human being? Are the aliens kind and polite to us or impolite and aggressive? So many questions about aliens come to us at the same time, however, no one can give a certain answer and convince all the people in the world. Whereas, comparing the supporting details of the both sides that aliens do exist and aliens do not exist, we can know which one is more convincing. Aliens do not exist because human never found any sign of them, it`s not convincing that the strange phenomenon is created by aliens and human haven`t found any comfortable planet like earth yet.

Point

Aliens may exist because some scientists believe it and spend money searching them and contacting them. Some astronomers like Frank Drake trust the existence of aliens and keep searching the signals aliens send. Frank Drake put forward the famous equation, the Drake equation, and he predicted that aliens do exist. The astronomers use the space telescope to observe the space and use some equipment to collect the radio signal from the outsides of earth to analyze whether the signal is valuable. All we have to do is to search them and find them out. If the space telescope can take a picture of aliens, how can we say aliens do not exist. All we need to do is spend more money in the improvement of the space telescope and use it to observe more planet in the deeper galaxy. Contact by radio wave seems to be the only way we can do now. And if the astronomers catch the signal sent by aliens, we can prove the existence of the aliens. To judge a signal whether is valuable and sent by aliens is not difficult. Distinguish from other noise signal, regular signals could bring some information. And continue the previous, if the signal is not sent by us human being, it could be sent by the aliens. Take me as an example, I will not open the door when strong wind hitting the door. On the contrary, I will open the door when my roommates knocking it. Because the previous one is the irregular noise and the later one is the regular sound. And according to this, we can conclude that aliens do exist. However, from we first start to observe the space and collect and analyze the signal till today, we have never gained any valuable information about the trace of aliens, our search for the existence of aliens is still zero.

Some scientists like Frank Tipler think the aliens do not exist and keeping searching them is a waste of time of money. Because more sophisticated equipment need more money to research and develop, spending so much money in to developing the equipment to search aliens is valueless. Hart (1975) agreed that we have never found any direct evidence of the exist of aliens, and with high possibility, we could be the only intelligent creature of our galaxy. Combined with the famous Fermi Paradox, if aliens exist, where are they and what Hart talked, Wesson (1990) shows that even the universe is vast, it still necessary to explain why there is no evidence to prove the existence of aliens. Besides, the Drake equation I mention before is just used to predict the existence of aliens by Frank Drake, only prediction is not enough to convince people. So although the suppose of the existence of aliens is beautiful and the work of searching aliens is still continuing, based on the fact of no direct evidence of the existence of aliens, we have more possibility to conclude that aliens do not exist.
