The Existence Of Extraterrestrial Life

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

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.

Before the sailor flybys in the 1960s, scientist thought Mars had water and life, even if it was just some sort of plantlike lichen. Mars has water, frozen underground and at the polar caps. There is (event(s) or object(s) that prove something) that this water has, in the past and present, flooded the surface in liquid from. Signs of wearing away can be

They have found that there might have been life on Mars at one point and there might still be little bits of life. All they have found so far is evidence of little tiny organisms and bacteria that were once on the surface.

Nearly half of our dear earthlings believe that extraterrestrial creatures and UFOs are real, but we still do not have a single piece of solid evidence that proves, aliens and flying saucers are in fact real. For the past few years people have been reporting alien sightings, but none of them have been fully proven. Scientists and other officials have proven them to be wrong again and again with government explanations. Aliens are extraterrestrial creatures that do not exist. In the cases of Roswell, area 51, and alien abduction, actual facts have proven that they were indeed misunderstandings by the public that caused people to think that there were alien and UFO sightings.

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.

The detected levels of nitrogen on Mars indicated that life possibly existed in the neighboring planet to Earth as these traces are essential to run all human life processes. But this was not the only discovery NASA’s Curiosity Rover made in 2015 -- in NASA/JPL-Caltech/MSSS’s photograph, the veins and nodules over a cluster of rocks on Mars were captured, suggesting that liquid water existed on the red planet (see fig. 1-2). Such discoveries can only prompt more findings to be made in the future as humans are one step closer to finding life beyond Earth’s boundaries. As NASA Chief Charles Bolden put it best, “Mars is a stepping stone to other solar systems” (Iacurci

First off, I’d like to say how people originally thought of the UFOs as Extra Terrestrial beings. Although I guess people looked over the fact that the material that the “UFO” contained a human made material. The people of Roswell turned this into a big story with a major assumption that the material came from space, but I don’t think they have much evidence for that. With all these people coming up with random ideas as to what may have landed in that farmers field in 1947,

The discovery of water on Mars and traces of it on the moon has caused many scientists and people to become thrilled. The evidence of water in other planets is hope for the possibility of life too. NASA is planning to send a rover over to Mars in 2020, to find any evidence of life (NASA In ESA's ExoMars Rover). The ExoMars Rover will be able to identify chemicals present in the atmosphere and in rocks and provide evidence for questions such as the existence of life on the Red planet (NASA In ESA's ExoMars Rover). Mars is one of the millions of planets that scientific community is hoping to finds signs of life on. The news of life on a different planet would momentous for people worldwide. It would be a discovery that would clear up several

Even though the three big reasons why aliens do not exist has been explained for this argument, there are still smaller reasons that add to the fact that there are no other existing alien civilizations other than ours here on Earth. One of those reasons is that governments do not give very much evidence supporting the existence of alien civilization. In fact, European governments have completely disclosed everything they know about UFO’s. The only evidence most governments give out to the public is testimonial evidence. There has never been any real hard physical evidence. Another reason is that scientists, in a sense, know that aliens can not exist, but they use the ridicule excuse as a cover up to explain why they do not admit UFO’s are real. Scientists are supposedly afraid of the ridicule they would receive if they would happen to admit aliens do exist. On the other hand, scientists lie and cheat to gain fame and fortune for all kinds of research and investigations. The discovery of UFO’s would make them big and famous, but yet all

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

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

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.

Frank Drake, an American astronomer made an equation to find the probability of finding aliens in our galaxy. The probability of humans finding extraterrestrial intelligence in our galaxy equals Nfpnef1fifcfL, where N equals the number of stars in the Milky Way, fp equals the fraction of those stars having planets, ne equals the number of those planets that can support life, f1 equals the number of those planets on which life arises, fi equals the fraction of those planets on which intelligent life evolves, fc equals the fraction of those planets where intelligent life developed into a technologically advanced civilization and fL equals the fraction of time a technical civilization lasts.

     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.
