Are We Alone in The Universe? Essay

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.

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.

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

First and foremost, over many years there have been plenty of eyewitness reports of things such as UFO sightings and even some claim to have seen aliens. There are some that claim they’ve been abducted by aliens such as in Travis Walton’s case, which is one of the more well-known stories. Of course, many people claim such abductions are simply hoaxes, but other accounts like videos and photographs are unexplainable. Just going on to Youtube and searching for UFO and alien sightings can bring up millions of

Other than that, all the story of aliens and UFOs starting to be an issue after the UFO crash incident in Roswell, New Mexico. It all started on June 25, 1947 when a pilot named Kenneth Arnold reported seeing several objects while flying near Mt Rainier, Washington. His descriptions of the objects that flew like geese and moving like saucers that you bounced it across the water and became the term "Flying Saucers", and thus the age of the UFO was born.

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

There have been many theories concerning what the universe looks like, how it became this way, and where it is going. The most popular theory that people hold today is that the universe began when all the matter ever present in the universe was contained in a tiny speck and that spec exploded. This is known as the Big Bang. This theory has developed a great deal since it was first conceptualized and continues to evolve today. Many different scientists have had a hand in this.

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.

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.

Extraterrestrial encounters of all forms and kinds leave some kind of evidence whether it is physical or non tangible evidence like a person’s story of seeing a flying saucer or possesses photos of the unidentified flying object. These forms of evidence aren’t always the most reliable as many are reported false and considered hoaxes. Ever since the incident at Roswell, any information or evidence that proves other worldly existence automatically becomes the center of attention and can bring an individual fame and even

What is life? This is a difficult question to answer, largely because life itself is not a simple concept. About four thousand five hundred million years ago the Earth collided with a planetoid the size of Mars. At this time, fragments orbiting the Earth formed the

Astronomers believed the Universe was created about 14 billion years ago. During that time, the entire Universe was inside a bubble that was thousands of times smaller than a pinhead, and it was insanely hot and dense. Out of nowhere this little bubble started expanding. This expansion created what we know as the Universe. In such little time the Universe went from the size of an atom to the ginormous galaxy we have that is continuously growing.

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,

     For half a century the subject of UFO has been discussed by scientists, ecologists, politicians, and common people around the world. It seems paradoxical, but the main question of their discussion concerns existence or non-existence of UFO itself, so many people is not sure that the very subject of their debate really exists. I share the opinion of those who do not believe in UFO saying that this phenomenon has not been scientifically proved, and everything its adherents operates is conjecture and fantasy, and disconnected stories of those who allegedly have seen UFO are far from scientific explanation of the event.
