There is a dozen of popular possibilities which explain the Fermi Paradox, each may seem impossible, but they are actually more likely than one would think. These are best split into two main groups. Group one possibilities explain that we have had no contact from higher life forms because they don't exist due to something else that must be going on. This something else is often referred to as The Great Filter. (Urban) The Great Filter Theory states that all life has many "filters" to pass through in its journey from pre-life to being a Type III Civilization. Most of these filters are easy to pass though and only kill off a few species of the millions that attempt to pass through. One of these filters is different, it is almost impossible to …show more content…
The first possibility is that other civilizations have already visited Earth, but long before we were around. Considering that sentient humans have been around for 50,000 years and we have had recorded history for 5,500 years, in the context of millions or billions of years, this is nothing, so they could have visited prior to our existence and never had a need to come back. This is also one of the most popular in pop fiction, with multiple movies being based around the theory that what the ancients thought were gods were actually aliens. The second possibility says that our galaxy is already colonized, but we are a rural area in which no one has any use of coming to. Many cases of this have been found in Europe's colonization of the Americas. Many small northern tribes had no idea that their whole continent had been colonized until a century later. The third possibility is that the whole concept of physical colonization would be an impractical use of resources to a Type III Civilization. They might build an empire around a small group of stars and build their perfect utopia. The fourth possibility is definitely one of the scariest. In this possibility, one predator civilization roams the galaxy looking for resources and life on other planets only to destroy them for their own benefit. This theory has led many scientists to suggest against sending messages out into the galaxy so others might find us. Much like Columbus's discovery of the Americas, it may not end well for the natives. This is again a possibility often referenced in pop culture. The fifth possibility is much like the fourth, except the predator civilization does not destroy other life for resources, but to keep its rule over the galaxy. It makes sure no other civilizations get to their level, or they risk being crowded out. The sixth possibility

In 1950, a man, Enrico Fermi, during a lunch break conversation he causally asked his co-workers an interesting question, “where is everybody”. (Howell, 2014) By which he meant, since there are over a million planets which are proficient enough to support life and possibly some sort of intelligent species, so how come no one has visited earth? This became known as The Fermi Paradox, which came from his surname and two Greek words, para meaning contrary and Doxa meaning opinion, about a 100 years ago. (Webb 2002) A paradox arises when you set undisputable evidence and then a certain conclusion contradicts the idea. For example, Fermi realized that extra-terrestrials have had a large amount of time to appear
The existence of life – Aliens, beyond our planet has been a controversial topic for several centuries, and is a debatable issue even today in the 21st century. What is our topic you may ask? Aliens, Do, Exist. According to theoretical physicist, Stephen Hawking, it would be improbable for life not to exist somewhere other than Earth. This is a bold claim, but there is evidence to support this statement. The evidence we seek is in the many Alien occurrences we have experienced throughout human history.

Some people believe we are not alone in the wide variety of planets, stars, and the solar system next door to us. Believing we aren’t the only ones stuck in space, but having more power than us where they might watch over us. The strong belief created a phenomenon more than the sci-fi culture itself; government cover-ups can’t hide these visitors anymore.
The thought of infinite space is a scary and exciting thought. The thought that stars, planets, and even suns exist beyond the sights of our strongest telescopes is a very intriguing thought. Some theories suggest parallel universes exist while others suggest that intelligent life is living exactly the way humans on earth live today on far away planets. Perhaps the most frightening and yet thrilling thought of all is the thought of extraterrestrial life amongst the stars, visiting earth, and every so often, being spotted or caught on camera. These interactions are considered extremely rare and witnesses to the events refer to themselves as lucky. Religions have even been created at the thought of aliens. The search for
Sure we've all seen movies and read books about extraterrestrial beings landing on the Earth and conquering the human race. And millions of us have viewed TV shows like "The X-files" and "Third Rock From the Sun." These forms of popular culture share a common thread -- extraterrestrial life. Yet the underlying question is, does the mass media take extraterrestrialism seriously? Or do they mock it? Or do they simply exaggerate its credibility? In the majority of these cases, the mass media not only takes on the third mode of exaggeration, it shifts focus from more important and serious issues such as extraterrestrial life at the cellular level. The media loves to play with the minds of viewers, making them believe in something which realistically is probably untrue.
In the “The Great Silence” Ted Chiang creates a thought experiment that helps the reader understand a possible answer to Fermi’s paradox. Fermi’s paradox poses two questions the first is why haven’t we encountered extraterrestrial life if there are billions of stars in the universe like the sun that are capable of sustaining life. Second, the universe has existed long enough for interstellar travel to be possible, but why hasn’t anything contacted us yet?
One of the qualities of the human race is that humans love to explore and find new things, like how Christopher Columbus found America. With most of our planet documented now, where do we have to go? The answer is simply one of the only places we haven’t yet (or may never) explore all of: space. Wars may be waged over land on earth, as there isn’t any new land to find there. So, we can go into space where unexplored land can be conquered and colonized. And while it may not seem like it, in the near future, it may be possible to colonize humans in space.
Jared Diamond author of “The Ends of the World as We Know Them” highlights the reasons for the disappearance of early civilizations. Civilizations like the Mayans, Incas and Aztecs once inhabited the earth for hundreds of years, However; when these advanced civilizations reached the pinnacle of their capability, they faced tragedies such as war, unusual weather, environmental deprivation, terminated trade markets and unscrupulous leaders who contributed to the destruction of their civilization. One significant idea portrayed from Diamond’s article is that there are many factors that threaten American civilization.
... highly equipped technology that humans do not have yet, while others insist these are just one of many hoaxes. Believing these are made by aliens will impact greatly on current society because the biggest religion in the world will be proved wrong. Some even say it is impossible for aliens to exist, but we must leave both options open, since we can never predict the future. Even a few hundred years ago, humans thought the earth was flat. Then we found out the earth is not the center of the universe. Recently, we can now travel to other stars and only collect samples. Because we know not even 1% about the universe, I think anything can be possible. Just a week ago, a news released that Vaticans are holding a conference for possible alien beings(fox). Maybe, we humans are just getting adopted to accept other intelligent beings as planned by unknown sources.
There was always a new horizon to conquer for an intelligent species. The first was the domination of small areas of land. Those small areas expanded into larger areas, and soon a dominant species claimed dominion over their entire planet. When space travel first became possible, this process had repeated itself. At first they made small colonies on neighboring planets, and moons. Over the years the galaxy and beyond had been surveyed. Technology had evolved to a point of where the entire Local Group, all 54 galaxies, millions of light years under control.
We always find extraordinary things such as UFOs too farfetched but wouldn’t it be easily possible for civilisations that are billions of years older, to develop such things? We have also seen evidence of extraterrestrials from paintings that date back to the 15th century. “The Madonna with Saint Giovannino” a very famous piece of art depicts the virgin Mary and a man in the background looking at a flying object which is in the shape of a Flying Saucer. This is very similar to the image we associate with a UFO today and it was before the idea of UFOs, could it have been extraterrestrial lifeforms visiting our planet? Sightings are also described in the bible, Sanskrit scrolls and even on ancient cave paintings. Religions like Buddhism and Hinduism believe we may reincarnate as beings of another planet, formally known as
Is there such thing as life outside of Earth? The building blocks of life are carbon, nitrogen, and oxygen. Those ingredients condense to form all living things, new stars and even new planets! So, who’s to say those ingredients didn’t form other life on other planets? Think about how vast outer space is. There are millions and millions of other planets, stars and galaxies! It’s not that far out there to think that there might be other life in space, in fact, some people even have stone hard evidence that supports the idea of “aliens”. I personally believe there is such thing as extraterrestrials, and I believe they have visited earth before. As a child, I remember my dad and I would sit around all afternoon watching alien documentaries or shows about people hunting aliens and searching for UFOs. When it comes to aliens people have so many questions; have aliens been to earth before? Are they currently living on earth? Are they controlling us? Does the government know? If so, are they hiding it from the public? There are so many questions you can ask but, in order to answer them, you have to
There is a popular belief that aliens walked the Earth in ancient times, and these theories have created quite a stir in the scientific community. Ancient alien theorists, like Erich von Daniken and Zecharia Sitchin, believe that extraterrestrials came to earth thousands of years ago. Some hypothesize that ancient aliens are responsible for ancient technological wonders, and that they helped to shape human civilization. Furthermore, the belief that ancient gods were in fact aliens, misinterpreted as gods by the ancient people. As it turns out, there is quite a bit of evidence to support some of these ancient alien theories. However, it is all subject to interpretation, as it has not been validated. Evidence used to support the ancient alien theory can be found all over the world in ancient geoglyphs, art, sculptures, architecture and text. A mesmerizing topic that has captivated millions of people, Ancient Aliens brings to life the possibility that we are not alone in the cosmos and gives us a new perspective on life existing beyond our planet by looking within our very own past history and civilizations.
