Often categorized as monster-like beings with animal instinct qualities and the urge to either destroy the human race or feast on human blood, ufos have taken in a big part of the nation's entertainment business, Alien vs. Predator, Independence Day, Cloverfeild, these are just a few of many films what Hollywood has delivered over the years as its perspective of what UFOs are but Since Ufos are usually described as these monsters, people often categorize Ufos as fantasy or nonexistence, when infect there is scientific evidence that there is extraterrestrial life in the universe.
People who have spotted ufos have described them as disk shape objects normally silver and a few hundred feet in the sky, just floating like a fish in mid air, this phenomenon isn't very new to us. There have been many cavemen painting of men on squared objects looking down at people, how did prehistoric beings even have the mentality of thinking of something so complex of their time, unless they truly did see that and recorded it onto their paintings. There have been also many other societies in history who have carved similar objects and shapes to the ones of the cavemen, one of which has been a great society and looked up upon for many eras, the Egyptians worshiped Tep Zapi, "the sky god" which according to their legend, these objects flew through the air in boats; which in this case might have been simmer to a disk, but since they were not aware of what a disk was the compared it to boats. After they came down, and brought law and wisdom, this might speculate that even after this object circulated Earth, they set foot on land and even made contact with Egyptians. There is even carvings of what people have claimed to see to this day of beings with heads shaped like an upside down tear drop and insect shaped eyes, there has even been rumors that the UFOs inspired the Egyptians to build the pyramids. The thought that Ufos have left a mark on land isn't the first time people have questioned it, there have been many signs of crop circles in the fields of England, at first crop circles may sound a bit fraud and pretend because many people have claimed to be the ones behind this scandal, when in fact scientists have conclude that the so called "man-made" crop circles tend to be very sloppy and distorted, but the actual complexity of the crop circles found are too geometric and beyond human imagination, to be thought up and made in just one night, in 1974 astronomer Carl Sagan sent out a message using a Arecibo telescope to try to make contact with any other sort of life beings in the universe, on the message it included the numbers one through ten, atomic numbers, formulas like sugar and other compounds that form DNA, a picture of an average man and the human population of Earth as well as a picture of our solar system, in 2001 a crop circle had appeared in Hampshire, England that replicated the message sent by Sagan in 1974, the fact that it was this message that was sent to space had scientist thinking that maybe someone or something did get this message after all, and in 2002 a strange reply appeared in Crabwood, England with a image of a face; form of an upside tear drop, and i disk near it with a code in a binary disk form, the same kind of sequence Sagan used. Many Scientist have wondered why these disk shaped objects wont just make contact with us, many have pointed out the Zoo hypothesis which scientists believe that UFOs treat us like a zoo and observe our development, it would be like giving a kid a ant farm, the ants have no idea whats going on outside of there compartment they are more focused in collecting food and maintaining the queen happy just like we do in our local zoos, the fact that we fear them for destroying the human race should be the least of our issue, there are being out there who have traveled to Earth for many years and have been spotted in history throughout earths development, if they have the knowledge to come up with interstellar travel, they would have destroyed us a long time ago, Earth is relatively young considering there are other planets out there that are double of earth's age, many forms of bacteria have been found in the planet mars as fossils and mars does have ice caps which are evidence that life may have existed in Mars before but just as microscopic figures. What makes you think that there aren't galaxies out there beyond the view of any telescope that carry the same traits as humans just more aged and more knowledge. Darwinists speculate that if alien life did exists on another planet, the evolve stages of evolution would apply to the planet hence making aliens look surprisingly similar to humans. Many painting, signs and carving of similar form as the one described can be found through many countries like North Africa, Italy, Egypt and countless other countries in different regions and also eras, the most recent claimed sighting was recorded on April 2010. A famous story about a couple who claim to not only witness a UFOs, but they claim to have been abducted on one. Betty and Barney Hill were a couple in 1961, they had been driving back home from a vacation trip, when they suddenly saw something pass them, at first they assumed that it must have been a helicopter or any other sort of explainable flying object in the sky, but they stopped the car and Barney went to investigate the object more closer, that is when he discovered that he was witnessing a UFO, he described it as being a pancake or banana shaped figure. After the strange object had appeared, both Betty and Barney Hill decided it was best if they kept this a secret until further notice. It was until 1961 when it was published in a local magazine, talking about their story and what had happened that night. After the media had covered this famous claimed sighting, Dr. Benjamin Simon; a well known psychiatrist from Boston, chose the Hills to be examined more on the event, Dr. Simon hypnotized Betty and Barney, always made sure that they were both hypnotized in separate rooms and always made sure that neither of them could hear the other in the process of getting hypnotized. When they were both hypnotized both Betty and Barney could remember the UFO experience, but although it was very vivid and repellent, Dr. Simon was forced to reactivate their amnesia at the end of each session. the strange part was that even if they did make it up, it wouldn't explain how both Betty and Barney Hill were able to state similar stories under hypnosis, when both weren't allowed to listen to what the other was saying in the process of hypnosis. They both said that they got carried aboard a disk-like ship or object and there were tiny men about five feet tall. They were questioned and "sent back." This famous story is still far by one of the most believable UFO stories to this day, after this story came out to the public, it made huge headlines nation-wide, there have been many movies based on this story and its whole incept as well as a twilight zone episode that reenacted what had happened.
Even though people claim to see the same thing all the time they have never caught any physical evidence, besides poor picture and video quality recordings, but even though many people have not seen them, Scientist have been determine to prove otherwise.
Scientist Paul Wrey came up with the anthropic principal in 1940's with a equation to show the possibilities of life on other planets. "N = R Fp Ne Fl Fi Fc L" is the equation and he explains that if "N" was the number of civilizations with we can contact and "R" the rate of star formation, there is about ten starts per year and if "Fp" was the fraction of starts that develop planets and "Ne" was the planets suitable for life, "F1" planets that developed life, "Fc" meant the civilization that could communicate, "L" meant the stage where civilization could process. Scientist have only connects the variables "R,Fp and Ne" the rest of the calculation is still undetermined due to insufficient evidence, because scientist need to find a way to observe how the life process occurs. But Scientists have came up with two hypotheses that can explain the origin of life.
The first one explains how scientists believe that some molecules might be capable to self-reproduce and develop into a combination of different compounds, but based on the calculation this is highly unlikely to happen, because even though some compounds that can be easily made in a lab, have difficulties reproducing on their own, and molecules like RNA who need hundreds of amino acids which are the few of many compounds that cant reproduce, can not be made without amino acids, so the possibilities of this happening is slim. The second hypothesis is the Copernican principle which is best defined as the principle of mediocrity, this principal assumes that we as a world of intelligent beings are nothing special, and that there is an ordinary mechanism that life is developed, but we haven't been able to unveil this mechanism. this hypothesis also believes that if there truly is aliens out there, it is impossible that they will resemble us as a society. Even though many people believe there is not sufficent evidence to prove the existence of UFOs, some scientists have made it clear that the possibilities of life on other plants are likely, there just isn't enough evidence and technology to support this claim, and since the media has brought forth the attention of UFOs into being like monsters and fearsome, it is not looked upon as a actual topic for scientists to study. it has been brought to our attention that they do not exist, but like Albert Einstein once said, "two things are infinite: the universe and human stupidity; and i'm not sure about the universe" this means to me that even though there might be an end to the universe, there will never be an end to human stupidity, if people claim to see objects seen 5000 years ago why do we still portray UFOs are false?
