Life Off Earth Anthropology

With all our knowledge of everything around us, overwhelming as it may be, there are still a lot of aspects that are unknown to even the smartest scientists. Did you know that humans know only 5% of the entire universe? Yes, everything we know about the Earth, the Milky Way, and all the planets is barely even a fourth of what comprises the entirety of the universe. Knowing that, it would be illogical to say that the creatures on Earth are the only forms of life in the universe. Today I will tell you about unidentified object sightings, close

Does life exist on other planets besides Earth? Has extraterrestrial life visited Earth recently or in our distant past? The notion of extraterrestrial life is a very intriguing subject possibly for as long as mankind has looked into the vast heavens gazing at the stars. Can one say that life on Earth was done by Mother Nature which some call evolution? Is life on Earth the result of creation or alteration by a higher power or being? Some people do believe that other forms of life except those on Earth do exist. Others consider it false because there is no absolute proof beyond doubts. There have been countless occurrences by individuals around the world of either being contacted or abducted by alien life forms. Many unofficial accounts describe the Earth as being visited by one or more alien species. These various alien species that possibly visited Earth may be interested in observing the development of the human species.

Throughout history humanity has been fascinated by the existence of extraterrestrial life. Today such ventures are in the development process and the discovery of life beyond our solar system, no matter how primitive, may soon become a huge(important?) scientific breakthrough. The three basic things that are required to consider a place even remotely habitable are water, a source of energy, and organic materials. Habitability also depends on other factors that must also be taken into consideration such as how close the planet is to its star (in the case of our solar system, the sun), how long the water and organic materials existed there, and the size and mass of the planet. One must not confuse habitable with inhabited. The term

We live in a universe that is about 46 billion light years old. In a world, as massive as ours there must be some form of extraterrestrial life out in the galaxy. For thousands of years ancient peoples, such as the Greeks, have wondered the same question. Are we alone? As our technology advances, things such as videos and photographs are surfacing of people claiming to see such alien life. Whether it is an unidentified flying object, or if it’s from someone claiming to see an actual alien, there are thousands of people that believe they have seen proof. Some also claim that the government is hiding things behind our backs, like the Roswell UFO incident for example. Though many people refuse to believe in the existence of alien life forms until they see evidence, the fact that multitudes of people have eye-witness accounts, the improbability that we are alone, and the idea that we have thought of aliens so long, bring forth the evidence that proves something is out there.

Aliens and life beyond earth has been a mystery for a long time. Many people and scientist have been looking for life outside of Earth, or just floating in the sky trying to get video of it. For all of human history we have been looking for extraterrestrial life, and these are the major events of finding, debunking, and moving forward to life on earth

James Green discusses in his speech the possibility of there being life beyond earth. Green starts off with a quote that is used in a lot of movies, books and television shows, “Is there life beyond earth in our solar system?” He follows this initial quote with one by Carl Sagan, an American astronomer, “It takes extraordinary evidence for extraordinary claims.” It is important for Green to use these two quotes as attention getters. He hooks the listener with his works and we begin to think if there really is life in our solar system then just on earth.

Exobiology is the science that is concerned with the search for life in outer space; it may be called as astrobiology as well. The search for life in outer space has consumed the imagination of the humankind for long time ago. Nowadays, humankind has made a progress and found major discoveries in the quest for life existence in the universe and outer space because of the advancement of the technology. However, in the past, exobiology was considered as a science without a subject, where the people and other scientists laughed at and ridiculed the famous scientist and biologist Joshua Lederberg when he originated the term exobiology. Some people argue that life exists elsewhere in the universe, however, others believe that life only exist on Earth. A new study reveals that our galaxy, the Milky Way, has 100 billion or so stars, where 17 billion of them are Earth-size alien planets, and probably many more. The huge size of the galaxy increases the probability of life existence in the outer space. Are we alone in the universe? This question has captured the imaginations of scientist, theologians, and astrobiologists. However, they don’t know the answer yet. Understanding the complete definition of life and how life originated, and determining the techniques used for searching for life existence in outer space and evidences found can help to answer the question of “Are we alone in the universe?”

Most astronomers and scientists seem firmly convinced of this fact. Although there is not any direct (or even indirect) evidence to support these claims that other sentient life is sharing the universe with us. However, this lack of evidence showing that extraterrestrial life forms exist is not proof that they do not exist. It just does not seem logical that our planet is the only place where life and intelligence could have developed. The odds are billions against life of some form being unique to the Earth only. The Earth is unimportant in the grand scale of things in the galaxy. By this I am referring to its' size and position in the universe. In fact, the American Association for the Advancement of Science suggests that the true question that we should be

Within the article Will We Ever Discover a Twin Earth? 20 Big Questions About the Future of Humanity, I found many of answers to the questions asked very interesting and thought provoking. With my unscientific opinion about there being other life forms in space already formed, I was glad to read Aki Roberge state that she believes that we will discover a twin Earth and that scientists have “found that planets around other stars are far more abundant and diverse than scientists imagined just a couple of decades ago.” The universe being as big as it is, I wouldn’t be able to believe that we are the only form of intelligent life.

The title of my paper is called, “Life on Another Planet.” The purpose of my essay is to explore the question of do aliens exist? I explained the possibilities that there could be other life out there in space. My conclusion was that in the future scientists could discover a planet where we can move to and live in, and even meet new species of life. As a result, scientists should develop more tools

Should we as humans expect to find intelligent life elsewhere in the Universe? There are many reasons for and against this concept, but first we should trace just how our terrestrial life started.

Life has continually perplexed and fascinated individuals since the dawn of mankind. The subject’s complexity is so great even over the course of human existence only a minute fraction of its mysteries have been unraveled. A phenomenon which has always intrigued scientists is the origin of life on Earth, and in recent years significant advancements have been made in the understanding of this enigma. This essay will briefly outline two theories regarding life’s origin on Earth to further comprehend why an explanation for this phenomenon has been so difficult to reach.

According to astronomical research and geological evidence, scientist indicate the universe is approximately thirteen thousand eight hundred and twenty billion years old. The first link to humanity started with a primate group called Ardipithecus. While our ancestors have been around for about six million years, the modern form of humans only evolved about two hundred thousand years ago. The age of the Earth is estimated about four point fifty four billion years because that is the age of the oldest rocks with fossil evidence of life on earth. The oldest rocks on Earth found to date are the Acasta Gneisses in northwestern Canada near the Great Slave Lake, which are four point three billion years old. The study of the origin of life on Earth, more specifically abiogenesis, is the natural process of life arising from non-living matter. Life on Earth is believed to have began from organic compounds about three point eight to four billion years ago. Despite several competing theories for how life arose on Earth scientist only know when life first appeared on Earth and are still far from answering how it appeared. Since it is hard to prove or disprove them, no fully accepted theories of the origin of life exists.

The argument suggesting life existing on other Earth-like planets has been present since man first looked into space and questioned his own existence and the existence of others like him. Today there are many theories on the existence of intelligent life elsewhere in the universe, but only one theory goes beyond them and into an even larger realm. The contents of this theory, known as the “multiverse” theory, suggest that humans on Earth live within one universe of many others that reside within a primordial vacuum containing many other universes (Jenkins and Perez). Each of these universes possesses potentially different natural constants and physical laws that govern them differently, thus calling forth some logical questions. First,

possibility of life existing on other worlds has been the subject of speculation for years.14 In
