Problem is that you cannot examine a UFO in a scientific laboratory.
There are some bright chances that the idea of UFO itself is nothing but some educated guesses or just wild imaginations! Tell me, is it possible to find out a logical explanation for reported sightings of a sudden object or light seen in the sky or on land. An object whose appearance, trajectory, actions, motions, lights, and colors do not have a logical, conventional, or natural explanation. Not only the original witness but even the scientists or technical experts could not explain the origin of these sightings. UFOs can be anything like a meteors, fading satellites, flocks of birds, aircraft, lights, weather balloons, and just about anything within the visible band of electromagnetism. But here let me admit, so far nothing has been positively identified as an alien spacecraft in a way that can be proved authentically by common sense and science. People have claimed their sightings with photographs of UFOs, but in most of the cases these photographs are blurs and forgeries. But whatever the physical evidences might deduce the fact remains that UFOs have become all most like legends. They are so popular that people do not care to go for logic’s, they just believe it!

2. YOU MIGHT BE CARRYING SOME ALIEN PARTS IN YOUR BODY! ( IMPLANTS)
If you think only Television soaps like X-Files can show a person is suddenly abducted by an UFO, then you are misguided. You may close your eyes and imagine this world is beautiful, no pollution no crime! But we know this cannot be true. In the same manner it is really important to be aware of the issue of extraterrestrial abductions and subsequent implants in some of the cases. Mostly we think of them as minor incidents of mechanical nature. But as you go deeper and dig into the matter; you will come to know that some of these implants have been placed in people’s astral, mental, and also in their etheric bodies. Implants come in many sizes and shapes. They also have many different functions. One is to suck you Light and energy. Some are used for telepathic control. Some block you from you spiritual goals. They can be found in the chakras, in the glands and organs, above the head – all over the body. It is difficult to believe but it is said that all most 8 out of 10 person on Planet Earth has implants, and that has been going on for the past 10 million years. You might feel frightened when we touch this topic, but there is no need for fear. These implanted people have been functioning with their implants and living their lives successfully for eons and will continue to do so. These ‘gadgets’ are usually implanted during childhood or at times of physical, mental, or emotional crisis or illness. Though one may function quite well with the ‘gadgets’ in their system but they do prevent you from operating at your full potential. Awareness about implants are yet to come up in the limelight. Very few people can accept them or see them. Except for the physical, mechanical ones. But since we are at the threshold of a new century, a new Age, no doubt implants will be taken seriously in the days to come. Hey, did you check yourself?

3. HOW DO THEY LOOK? (IMPLANTS)
Once you come back from your holiday trip of ‘alien world’, you should check your body thoroughly. You might receive scoop marks on the body particularly on the legs. If not scoop marks then you might get a series of red dots or triangles, this could be found on any part of your body. Beware, you might also have radiation burns which can to blindness and cancer. These implants can be seen in your MRI reports it might be placed in your brain area near the optic nerve. Implants are often retrieved from nasal passages and other parts of the body. They might look like a tiny computer chip with 3 little wires protruding from one end, or a like a little glass chip. Implants are wire-shaped and under an electron microscope will look like a complex structure containing many different layers. They are composed of a variety of metals and alloys. The implants have highly magnetic qualities and glow fluorescent green when exposed to ultraviolet (UV) light. Implants can be anything, they might be some transmitters or receivers of some sort of signal. It can also be some sort of monitoring device that receives signals from the abductee’s nervous system. But til date we have no concrete evidence as far as the manufacturers of these implants are concerned. Who implants them? Who makes them? No body knows. But they are out there….experience them!

4. WHAT THE HISTORY CLAIMS ?
Not just in fairy tales apart from that there are many myths, legends, and stories that tell of strange things seen in the sky or beings who came from the sky to help humans develop civilization. Say for example, in the 1890s, people across North America watched strange dirigible-shaped airships with very bright searchlights flying above their farms and towns. People went so far as claiming to meet the airship pilots. Modern researchers disagree about the authenticity of these accounts. They claim these airship reports were hoaxes spread by local “liars’ clubs” or sensational stories written by creative journalists hoping to sell papers. But there are few ufologists who are convinced these airship sightings represent the first reliable UFO reports in history. Fighter Pilots saw strange, glowing balls of light flying next to their airplanes during World War II. These lights were called as “foo fighters”. The term came from Smokey Stover, a popular comic strip at the time. At first the Allied command believed the foo-fighters were secret German weapons or surveillance devices. Only after the war did they discover that German pilots had also seen the glowing lights, which were thought to be American or British secret devices! People of and experienced a number of unusual aerial objects during the summer and fall of 1946. They were given the name of “ghost rockets” . Swedish and Norwegian strongly believed that they were secret Russian weapons developed from the German wartime rocket program. Officially the Swedish defense ministry stated that 80% of the 1,000 ghost rockets could be explained by natural phenomena, but about 200 cases could not be explained as either a natural phenomenon, Swedish or Russian aircraft, or misperceptions.

Since most of the modern researchers question about the authenticity of these sightings; so they claim modern UFO era started on June 24, 1947, with the sighting by businessman and pilot Kenneth Arnold. While flying his small plane along the Cascade Mountains in Washington state, Arnold saw 9 crescent-shaped objects flying along the contours of the mountains. Although he saw them for only a 3 and a half minutes, Arnold knew they were not regular airplanes. He radioed in his report, and when he landed at the airport, reporters were waiting to ask questions. He described the motions of the objects as “like a saucer would if you skipped it across the water.” This is where the term “flying saucer” came from and rest is history!

5. SOME THOUGHTS THAT MIGHT EXPLAIN EXISTENCE OF UFO
1.UFOs Are Alien Spacecrafts
The most popular worldwide theory, or belief, is that UFOs are spacecraft built and operated by aliens from somewhere else in outer space. One more probability is that UFOs are portals or “wormholes” that connect different parts of our space-time eternity. They are used by intelligent beings to move between different points in space-time. This intelligence behind UFOs comes from outer space. But contrary to this thought are those people who believes UFOs originates in another dimension or on earth itself. One school of thought strongly believe that UFOs are created by secret groups of scientists who have developed technology beyond the current capabilities of mainstream science.

2. UFO’s Are Natural Phenomina
There are a major section of believers who thinks UFOs are unusual natural phenomena. A propagators of this thought cites the ‘Ball lightning’ as an example for their support. They argue that geological stresses in the earth’s crust produce glowing balls of ionized gas that are ejected into the atmosphere. They think that the PLASMA, the properties of this gas, may have strange effects on the people that come near it; plasma may stimulate areas of the brain to produce vivid hallucinations, which might be the basis for abduction cases.

3. UFO’s Are Outcome Of Stress
Yes, this is also another view that UFOs are the result of psychological or sociological factors. This view is mainly advocated by the skeptical of the existence of UFOs. They argue that all sightings are really misperceptions of natural phenomena or conventional aircraft. According to them these misperceptions are the result of the witness’s ignorance, emotional state, or psychological health, or caused by unusual environmental conditions adversely affecting an individual’s perception.

In fact the stresses and upheavals in modern society have created a need in many people to establish “contact” with UFOs or aliens. Such a need exists because modern society has rejected traditional values and beliefs, leaving individuals adrift with no direction or hope. Through their belief in UFOs and technologically superior aliens, some people can place their faith in something or someone who can help humanity solve its problems and restore purpose to the world. Interesting! Isn’t it!

6. CATCH THEM IF YOU CAN
No doubt there are some authentic pictures of UFOs. But most of the so-called UFO photographs are really natural phenomena like strangely shaped clouds or are light leaks in the camera or flaws that were introduced when the film was developed. Some photos are deliberate hoaxes made by people who want you to believe they have seen UFOs; for any number of reasons, such as fame, money, or to promote a religious or philosophical viewpoint.

Some of the best, or most accepted, UFO photos were taken in McMinnville, Oregon, in 1950; in Rouen, , in 1954; off the coast of in 1958; and in Lubbock, Texas, in 1951. There are also videotapes of UFOs taken in the Hudson Valley region in New York, and in . The UFOs come in all shapes and sizes. Most common are the NLS or the nocturnal lights. Some are only small spots of light that move in strange patterns across the night sky. Even faraway objects like a saucer-shaped, seen in the daytime are called DDs or daylight disks. CE (Close Encounters) If the UFOs approaches within 500 feet to witnesses these sightings are called close encounters. There are 4 types of close encounters, designated as CE-1, CE-2, CE-3, and CE-4, this is refereed to the abduction cases.

If you are the lucky one you might see UFOs that are shaped like saucers, boomerangs, spheres, diamonds, cigars, triangles, or other strange shapes. They will definitely have bright lights, sometimes white or red, other times multicolored. You don’t have to run after a UFO, their speed varies dramatically. They can hover silently for a long time then instantaneously fly off at great speeds–certainly much faster than conventional aircraft. They can move slowly across the sky, or perform unbelievable maneuvers, such as right angle turns, at incredibly high speeds. The bottom line is if you have a date with a UFO you will enjoy the date. That is confirmed!

7. DETECTION OF UFO’s
You must be wondering if there is any method of detecting UFOs. Yes, we have RADARS and there are cases in which UFOs have been tracked by radar. But time has proved that radar is not considered a practical surveillance technique for UFO detection. Radar, including the sophisticated systems of the FAA and NORAD, has many shortcomings that limit its value to UFO research. A UFO may be too low for it to be detected or too fast to appear on the radar screen for more than a few sweeps of the antenna.

UFOs that hover or move erratically may be filtered out by a radar’s sophisticated computer system as ground scatter or noise. Also, planes with transponders return stronger radar signals than targets not so equipped, and radar’s are often tuned only to transponder signals. It is also possible that UFOs might not return radar signals at all.

But the fact is one Radar-Visual case is more significant than dozens of nocturnal light reports for increasing our understanding of the UFO phenomenon. So we got to wait and follow those radar reports very closely, in case.. in case.. in case! Who knows!

8. DO WE REALLY HAVE SOME FRIENDS OUT THERE.
This is one of the most interesting question for most of the people on this earth. There have been many fanciful tales about life on other planets, most scientists search for intelligent life by using radio telescopes tuned to detect the emissions of other technologically advanced civilizations. Projects involving the search for extraterrestrial intelligence are referred to by the acronym SETI.

One of the first organized attempts to discover extraterrestrial life was Project Ozma, named after the queen of Oz. This project was initiated by the American radio astronomer, Frank Drake. The project tuned its telescopes to detect radio emissions from nearby sun-like stars, such as Tau Ceti and Epsilon Eridani. Frankly no signals proving the existence of intelligent life were ever detected. But some valuable information about the universe was discovered. Since Project Ozma, other attempts have also been made to detect extraterrestrial signals, with one of the longest-running efforts occurring at Ohio State University.

Despite the lack of success in discovering extraterrestrial signals, most astronomers consider the probability for extraterrestrial life to be very high. This conclusion is based on the Drake equation developed by Frank Drake. Seven factors are used in the equation to determine the probable number of technological civilizations able and willing to transmit and receive radio signals. These factors include:-

1. THE RATE OF STAR BIRTH
2. NUMBER OF PLANETS AROUND A STAR
3. PLANETS WITH LIFE
4. SUPPORTING ENVIRONMENTS
5. INTELLIGENT LIFE
6. COMMUNICATING SOCIETIES
7. CIVILIZATION LIFE SPAN

Many scientists out rightly reject the idea that extraterrestrial life exists. They argue if at all any extraterrestrial life exists in the universe, they should have arrived here by now. So where are they. The argument further states incase the extraterrestrial intelligent life exists, we would have the evidence for its existence by now because the age of the earth would have given the extraterrestrials enough time to reach here. It is very true that if intelligent beings exist elsewhere, many factors may have prevented them from contacting us, or they may have simply chosen not to do so. Then again, the possibility exists that the extraterrestrials have reached the earth. Considering all the arguments fact remains that it is yet to establish a confirm idea if they are out there or not. Have you seen them.
