Extraterrestrials Can the Earth be the only place in the Universe that harbors life? Most astronomers don't believe this is true. Certain statistics in the Universe provide evidence that living beings may be common place through out the universe, on planets of other stars besides the sun. In this paper I plan to discuss the various viewpoints of those that believe that extraterrestrials exist and have even been visiting Earth, and the viewpoints of skpetics that believe that aliens don't exist and have not been visiting Earth. To get into the topic we must first start at the base of the subject. First the question must be dealt with of life being only indigenous to planet Earth.
One of the most basic materials that are essential to form life are basic carbon compounds. These carbon compounds are very abundant throughout the Universe. Carbon compounds exist not only on planets but on comets and free floating asteroids and gas clouds in space. Although, even with the abundance of all these compunds in the Universe the chances of these compounds forming into living beings aren't so great, however it is true that the odds of carbon forming into life sustaining compounds is greatly increased with an increase in time. The Universe works on a basis backward to the human way of thinking.
The Universe becomes more orderly with time while we would tend to think that time breaks down structures. This means to us that the chances of life evolving on any part of the Universe increases as time moves forward. Another factor that is necessary for life evolving is a Star's size. Our Sun is a very ordinary star in terms of it size and temperature. Statistics show that there are billions of stars like the sun in our galaxy alone.
( Henbest & Couper, 1989, paragraph 5 ) Life evolving in one of these star systems may have developed in the same way humans have. Philosophers have argued for centures about how to define life. If we study living things on the Earth, we find that there are some very basic characteristics that will guide us when we consider life elsewhere in the 3 Universe. ( Henbest & Couper, 1989, paragraph 7 ) Life on Earth shows immense diversity. From organisms such as sea slugs to the human being.
All life on Earth are made up of the same basic units, cells. Each cell is built up from chains of carbon, the most important element to our existance. Within our own solar system only 1 out of 9 planets defines as having life as we know it. According to some scientists Mars our sister planet may have started to harbor life early in its evolution but some catastrophic event caused Mars to become the barren frozen wasteland it appears to be today. for our solar system alone 2 out of 9 planets that have or may have had life aren't very bad odds for extraterrestrial life throughout the Universe. Most skeptics of extraterrestrial life or at least of intelligent extraterrestrial life existing are those that believe in Creation rather than evolution. Creation, in Christianity states that in seven days the Sun, Earth, and all life on Earth were created by a superior spiritual being, or God.
This paper was not written to argue whether any of this is true, or debate the existance of God but just states the opposing views of those who believe intelligent life is non-existant elsewhere in the Universe. I believe that the human race would very much like to feel that we are the only intelligent life forms in the Universe. To believe that we are the only intelligent life forms in the universe makes us feel special and gives our life a purpose that no other being can experience. To have proof of other intelligent life existing would give humans such a cultural shock that some have said that our social, economic and political systems would be thrown off balance.( Cornet, 1995, paragraph 10) Religious, and social chaos would become rampant. To wrap up the question outlined we must touch on the question of whether E.T's have been visting Earth. As stated in the previous paragraph, for the human race to come face to face with 4 a more advanced alien race would be so much of a cultural shock that our governmental, economic, and social structures would be broken down.
Solely based on the new knowledge of all persons on Earth that we are not alone and have never really been. Religious teachings and basis of human uniqueness would have to be revised, leaving many many people of the world to breakdown. Imagine that you have just been told, rather have just come to the realization that everything you've ever known about life and creation has been a false teaching. That you have no special purpose, that you are one of perhaps thousands or millions of intelligent beings in the Universe. I can imagine that one would collapse based upon this knowledge. This is the most important fact that actually is in favor of the existance of an advanced race visiting Earth. This is what leads many E.T.
believers that intelligent life throughout the Universe is abundant and we have been visited by an advanced race of beings. The advanced race of beings would have the knowledge that solid proof of their existance would break us down socio-economically and therefore have managed only to slowly hint their existance rather than appearing to us and saying We do exist. Many people who are believers of E.T.'s have had experiences or profound symbols shown to them that lead them to believe that E.T's are visiting Earth. These who are believers believe strongly that these E.T.'s are here to help mankind. They are here to help man- kind spiritually advance themselves.
An example often used to advocate these aliens helping mankind is our sudden boost of technology within the 19th and 20th centuries. Many believe that one day these E.T.'s existance will become obvious to us and they will show themselves for all to see. This will not happen anytime soon I would imagine because we are still maturing socially and spiritually, to have such an experience. The E.T's are preparing us few by few to eventually let their presence become known. It is not only those who believe in Creation that doubt the existance of E.T's visiting Earth, 5 scientists are also among some of the most substantial skeptics. Scientists share the same views as Religious figures in one aspect, that no E.T's are visiting Earth.
Science and Religion are finding a common view for once in history. Although scientists are looking at the situation in a different aspect, Scientists believe that an alien race could never reach Earth because of the enormous amount of energy that would be required for traveling across disctances in space. To set up a scenario The diameter of the entire Milky Way galaxy is about 100,000 light-years. Let's assume that an intelligent species happens to reside on a planet 5,000 light-years from Earth, and that 1.5 billion years ago their starships were capable of cruising at 10% of the speed of light. If they traveled only 1 light-year at a time, with each trip taking about ten years, and they rested or consolidated for a little less than 300,000 years before setting out on the next 1 light-year journey they still could have reached Earth by now! The answer to the question is T i m e .
