Are We Alone? The Question of Extraterrestrial Life

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

One might be lead to believe that after all of these hundreds of years, aliens would have been seen in the flesh instead of floating over the Earth’s atmosphere for all this time. The point is, there has not been one single sighting of an extraterrestrial in person after all these centuries and because we have not seen one single alien being in person all the way up to this point, there is no way they exist.

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.

I am sure that everyone of you have heard about aliens and UFOs. Indeed, we all have heard about the famous case of aliens and UFOs in Roswell, New Mexico. Most people might be interested in the topic of aliens, but I know that the majority of you just think of it as rumours and the existence of them are impossible. Therefore, I am standing here in front all of you to make you change your perspective. I am strongly confident that I have found the evidence of their real existence to convince all of you.

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.

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

Mars has water but it is frozen in the planet ice caps and under the soil. The atmosphere on mars is weak due the very high strong winds that occur. The surface temperature of the planet is freezing and the water on the surface of planet evaporates other than the ice caps due to the low atmospheric pressure of the weak atmosphere. According to brightkite.com, “Even with the bad temperature, weak atmosphere and said frozen water there still prove that there is life on Mars because there evidence saying that Mars’s living organisms could be sub surface ("'Strongest evidence yet to there being life on Mars'"). This means that the living organisms do have a chance to live and since there is water, wind, and cold temperature, this allows living organisms to breathe and exist inside the interior of the

"Water is key because almost everywhere we find water on Earth we find life," NASA's Web site. However, we are still unsure life existed on Mars.

Aliens have fascinated and enthralled many generations of people. The subject has plagued popular media and the scientific world since we found out about the other planets in our solar system. As Stephen Hawking once said, “From the aliens’ point of view, what’s the point of crossing vast tracts of the universe in a hi-tech ship just to abduct some lone earthling? … And if governments are involved in a cover-up, they’re doing a much better job at it than they seem to do at anything else”(“Into the universe”)! While the possibility of alien life is a matter of controversy, scholars and scientists alike have brought their own facts and opinions out. All while searching for the answers somewhere in the cosmos. However hard it may be to believe,

For so long, people have been trying to grasp the idea that maybe we are not the only intelligent life in the universe. There has been an overbearing amount of evidence that some will label as real evidence, and some will label as fake. Ex- government workers have come out and admitted to knowing about evidence and that there are real extraterrestrial beings out there and that there are many possible reasons as to why we have not completely encountered them yet. Many people say this whole idea of aliens is not real and that we are the only life out there but that is a little hard to believe which is why there are also many other who do believe. Whether extraterrestrial beings exist has been a topic of debate for a very long time as well as the debate of whether the government knows and is hiding it from us, and there is lots of evidence and proof from NASA and Maryland alone.

One of the main Methods used in trying to find extra-terrestrial is the technology we have and improving. By sending satellites into space to explore the universe we are find thousands of planets and possibly planets that could be a second home to earth if needed. Though it’s taking years and years to explore, you never know if there is any other life out there. Before satellites there was the use of telescopes which these are used all the time to discover stars and possibly planets if they are able to look that deep in space.

The biggest question we all ask ourselves at one point in time or another is, are we really alone in the universe? Many believe that all known encounters and evidence is either false, a hoax, or an attempt at fame and glory. True believers stick to the physical evidence and hard facts that follow these mysterious encounters. One specific event that occurred at Roswell, New Mexico in 1947 has baffled theorists and experts for generations and will continue to leave a controversial standpoint on what really may have occurred. This occurrence in particular has left a lot of unanswered questions about extraterrestrial existence due to the fact that most of the evidence collected from the incident is to either to old to be a credible source or the government has covered up the evidence and left a false influence behind. Overall, how has outside influence altered personal encounters and experience with extraterrestrial contact with relation to the Roswell Incident?

The idea of extraterrestrials existing and having visited Earth is a long shot, which made scientist Enrico Fermi question their existence, and that is how the Fermi Paradox was created. Enrico Fermi questioned the idea that since the Universe is billions of years old and billions of light years in diameter, extraterrestrials must exist somewhere and have visited Earth. Scientifically, there isn’t enough evidence to prove that extraterrestrials exist or have existed throughout our universe, but this hasn’t stopped millions or even billions of human beings from believing in them. There are countless of possible solutions to the Fermi Paradox, but all are hypothetical. The first possible and most popular solution to the Fermi Paradox is that

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).
