Argumentative Essay On Extraterrestrial Life

The United States government hides aliens from the citizens. They hid area for as long as they possibly could and still refuse to allow us any insight as to what is within. They claim sightings are military testing’s or that what some saw was never there. Looking at our technological advancements over the past few decades how could this be possible.

Alien invasion has been on the minds of many, and it is not something to take lightly. Aliens are real, the United States government has confirmed this, and these craft may be even closer than some claim. Unexplainable UFO sightings have been on the rise, popularized with the crash at Roswell, and they are not going anywhere. The fact that aliens are involved in these sightings is indisputable, but there are people who refuse to accept the truth. Many people state that Area 51 is just a “military base” and Roswell was just a spy balloon crash, but there is proof that there are aliens involved in both Area 51 and Roswell.

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

There are several different meanings to the word “alien.” An alien could be a resident born or belonging to a different country, a foreigner, a person who has been excluded from something, or a creature from outer space (extraterrestrial). For this argument, a creature from outer space would be the appropriate definition. Many believe extraterrestrials do exist. Many even claim to have seen aircrafts belonging to these extraterrestrials. There have been thousands of “sightings” of unidentified flying objects in which many believe do not look like or belong to anything Earthly. A lot of these sightings have not and can not be explained. Major governments around the globe will not come out and tell the public

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

“NASA has made statements recently that suggest that the discovery of aliens is a matter of when, rather than if.” (newsweek.com). NASA even announced an indication that there may be life on one of Saturn’s sixty two moons. “The Cassini spacecraft orbiting Saturn has already detected underground saltwater oceans on the moon Enceladus and Australian National University astrophysicist Brad Tucker says he is “ninety-five percent” sure that NASA will announce it has discovered changing levels of methane in the atmosphere – a phenomenon driven by organic life, at least here on Earth.” (nypost.com). “Jupiter's tiny moon Europa is scarred with brown veins that are suspected to

So, what are aliens? Aliens are exterrestrial beings that allegedly live in outer space and did not originate from Earth. Outer space is incomprehensibly massive. The galaxy in which human beings live is referred to as the Milky Way, and there are an estimated 100 billion planets in that one galaxy alone(SPACE.com Staff). Seth Shostak, an American astronomer and a Senior Astronomer for the SETI Institute, argues, "If we are the only intelligent beings in the galaxy, or for that matter in the universe, then we are truly a miracle." According to SETI.org, The SETI Institute is a research organization whose mission is to

In even the most primitive civilizations, the extra-terrestrial has had immeasurable influence on society. Mankind has always had an urge to explore the great unknown, and answer the most fundamental questions of our existence. Space exploration deserves not only to be a top priority in our nation, but much more funding than it already has, because it is rooted with history that has taught us many things and will continue to do so, it will help us advance technology beyond the scope of commercial innovation, and it can answer the greatest questions that every civilization has tried to answer.

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?”

Abstract: Scientists claim that other life forms do in fact exist based on probability. The conditions necessary for life are likely to be present on various other planets. Signs of possible life have been found in material from outer space. Much research has been dedicated to proving the existence of life on Mars. SETI is a program entirely dedicated to finding and establishing communication with extra terrestrials. If other life forms are found, communication with these beings will be a difficult task. Laws to protect humans from the dangers of extraterrestrial beings are already in effect. Although contact with alien beings has not yet been made, technology today may make it a reality in the near future.

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

In reality, many scientists were skeptical of both UFOs and of alien life in general; they contended that interstellar travel would be easy for advanced civilizations, so the lack of overt contact disproved alien existence. Yet most UFO opponents do believe alien life exists out in the universe, just not here. So they defend the near impossibility of interstellar travel, which contradicts a considerable portion of the scientific community (Thompson, 1990).
