Does Extraterrestrial Life Exist In The Real World?

The universe is huge and if it's that big it can hold many things including aliens. Many people report being abducted or seeing UFO’s. People have reported, have physical, or have heard aliens to prove they are real.

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

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

I believe that Aliens are real and have been to Earth. I may not have seen a UFO before but if you really think about it the universe is so big you think we are alone in this universe? Even if its plant life or some other type of other living thing. Many people don’t really like to talk about alien sightings because people who don’t believe in it call them crazy.

Is our universe unique? From science fiction to science fact, there is a proposal out there that suggests that there could be other universes besides our own, where all the choices you made in this life played out in alternate realities. So, instead of turning down that job offer that took you from the United States to China, the alternate universe would show the outcome if you decided to venture to Asia instead.

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?”

As science has progressed over the years, there have been many forms of exploration and discovery to find the answers we seek. One of the best examples are the Apollo space mission that were done by legendary astronauts and scientists. There have been many individuals over the years that wanted to know what was in space, but scientists now have the technology to experiment machines that can easily answer the questions of the universe we have. An article by Ronald J. White talks about how these missions have been accomplished for more than 40 years and how these events have made advancements on how people are able to travel through space when discovering the worlds that lie beyond our planet. After so many years of research, we have found so

This universe is so vast, diverse, and complex that makes it hard to think that we are truly alone out here. There are more than 100 billion billion earth-like planets, which makes about a hundred earth-like planets for every grain of sand in the world (Urban)! But if that’s the case, why haven’t we encountered any extraterrestrial beings? It’s strange how the possibility is off the charts, but because we’ve got nothing so far, we’re not even sure if they exist. So… where is everybody?

Among the billions of stars in each galaxy, many have planets that revolve around them. At least a few are bound to be of the right size and have the correct spatial orientation with respect to their star to allow life to grow. We believe this because life exists on the Earth. Astronomers have concluded that there must be hundreds of billions of other stars with conditions approximating those of the sun. Therefore there could be a million earth like planets with advanced civilizations in the Milky Way galaxy alone (Stilley). It is very probable that there is intelligent life elsewhere in the universe.

The most likely as of today is exoplanet Kepler-452b, which is about 1,400 light years from Earth (4). Kepler-452b orbits a similar star as Earth, orbits in the habitable zone, and is only thought to be 1.6 times the size of Earth (4). It is also rocky. The planet meets all of the criteria to be life-friendly, giving believers in extraterrestrial life hope. Many other planets similar to Earth have been discovered (5). Another indicator of life in the universe can be found here at home. Extremophiles live in conditions that humans have previously thought to be uninhabitable, such as the Middle East’s Dead Sea and half a mile under Arctic ice (6). Extremophiles show that even in places that humans cannot survive, it’s still possible. They provide evidence of the hardiness of life, which can only aid the argument of life elsewhere in the

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).
