Intelligent Extraterrestrial Life Essay -- Science

Intelligent Extraterrestrial Life When I look up at the stars at night, I just have to wonder who or what is looking back at me from some distant planet in some distant galaxy. We’ve all probably wondered what lies beyond our small, self-contained little world. The question many have pondered is whether or not there is intelligent life beyond earth. In the words of Metrodorus, a Greek philosopher of the fourth century, "To consider the Earth as the only populated world in infinite space is as absurd as to assert that in an entire field of millet, only one grain will grow." I believe that intelligent extraterrestrial life does exist. Critics of the theory of intelligent life beyond earth will argue that there is no such thing because they’ve never seen a "little green man." There are those who want proof of extraterrestrial life before they can accept the fact that there is any life besides what is on our Earth. They have a point. I’ve never seen an alien. I’ve never talked to anyone whose had a "close encounter." Sure, we’ve all seen the shows on TV with convincing footage of flying saucers, but we have no actual proof of intelligent life dependent from earth. It is true that we have no evidence of intelligent life beyond earth, but to claim that none exists because we’ve never seen aliens is like saying that the atom doesn’t exist because you can’t see one. We who have a grasp of our physical surroundings, and a basic knowledge of chemistry realize that the atom is the basic building block of matter. Those who say that there is no intelligent life other than our own need to realize several things. First, our universe is infinite. This leaves literally infinit... ...ence, why is our government so concerned about it? Although we can’t prove the existence of intelligent life beyond earth, it is very likely that it does exist. When one considers the vast infinite universe we live in, it would be completely foolish to believe that life on earth is unique. It is not just me who says that other intelligent life exists, though. Many scientists and philosophers have speculated about life on other planets for centuries, and today the search for life is a major driving factor in space exploration. Extraterrestrial life is not just an idea reserved for those who watch The X-files every night with all the lights out, it is an important concept in our current space-age, and to ignore the fact that extraterrestrial life would be like those of our ancestors who refused to believe that the world was round.
