Alien Life: Examining the Evidence - Argumentative Analysis
There are some strange phenomenon existing in the world that people could hardly explain then, making people put the responsibility on aliens. UFO, the Unidentified flying object, is often used as the evidence of the existence of aliens by many people. Crop Circle also seems strange and is regarded as the creature of aliens by many people. What's more incredible is that there are people who claim that they have been abducted by aliens. And according to such strange phenomenon we have heard about or meet with, there are more and more people believe that aliens exist. However, attribute the reason to the aliens is not convincing and even foolish. Strange phenomenon could be just something we could not explain now but it can be revealed in the future.
Imagine that the first time magic come into people`s life, everyone is surprised and no one know how the magicians can do that. However, magic could be explained by science. Phenomenon like Crop circle, we just don`t know how it happen. Taylor (2010) mentioned several possible explanation for the Crop circle like the cyclonic winds, using microwave generators, electromagnetic – hydrodynamic “plasma vortex” and human pranks. Although Taylor do not give the certain answer to the produce of Crop circle, we can still know that Crop circle is created by aliens is not convincing. As for the aliens’ abduction, Newman and baumeister (1996) did a research and they summed up the cause that is hypnotic elaboration, extraterrestrial sadomasochism and spurious memories, and the motivation of then could be escape self. Based on this research, we have reason to believe that the argument of aliens’ abduction is not convincing. Thus we should treat the strange phenomenon rationally and search for the scientific explanation of it instead of attributing the reason to the aliens and taking it as an evidence. So although the strange phenomenon is tried to be used as the evidence of the existence of the aliens, these evidences actually is false and not convincing, thus we have more possibility to conclude that aliens do not exist.
Aliens may exist if we can find a comfortable planet like the earth which can provide the necessary conditions for the growth of life. According to Moore (2013), to start life, it is necessary for the carbon-based and band together with other atoms, which finally form the large, molecules, and then water, atmosphere and temperature bring about the birth of life. Also Levin, Scott, Cooper, and West (2017) show that based on the theory of natural selection, extraterrestrial life should undergone self-copy, natural selection, major transition with restrictive conditions. Combined these two researches, if we find a planet with the condition mentioned, we may have large possibility to find aliens. In the research of Cassan, et al. (2012) we know that there are so many planets in the universe, and only in the Milky Way, this number is over 100 billion. We have reason to believe that we can finally find the aliens in the universe. The NASA Astrobiology Institute is found to explore the living conditions on Earth and elsewhere in the space. In 2015, Kepler-452b, 1800 light-year away from the earth, was found by NASA, which is regarded as the most Earth like planets. It seems that Kepler-452b is the answer we have been searching for years, and there is almost just one step away from finding aliens. But is it the fact? From their research of Kepler-452b, we know the diameter, temperature and many other data of this planet is just the calculations of scientists, due to the distance it may not be the fact. At same time, they do not mention that all the necessary conditions of life exist on this planet. They just predict. Again, prediction is not enough to convince the world. So in a way, at least now we still find no planet with comfortable living condition for aliens, let alone the existence of aliens. Thus even the suppose of finding a comfortable living planet is beautiful, based on the fact that we haven`t find any convincing evidence of such a planet, we have more possibility to conclude that aliens do not exist.
To make a conclusion of the whole essay, whether aliens do exist or not have been an argumentative topic since last century. Both of the two side have their supporting point. However, comparing the two supporting points, we 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 have never found any comfortable planet like earth for aliens to live yet. All I hope is that we can find more convincing evidence to prove the existence of aliens, but if there is not, we can only believe that we are the only intelligent being in the universe.
