Aliens: a Reality Are aliens real? Are they coming to earth?

These are questions that have haunted scientists and common people for ages. But there are several, who are firm believers in the existence of life on other planets. There are strong propagators of the theory that the aliens are coming and have in fact been regular visitors to earth. Combine this with the very commonplace reported occurrences of UFO sightings and alien abduction stories and one cannot help but answer in the affirmative to the question, are aliens for real? Scientifically, there have been several probes in order to shed light on this complex probability. One of the foremost research projects in this area has been the SETI or the Search for Extra-Terrestrial Intelligence. This is the name for a number of activities that various people have undertaken in order to search for alien life. They use radio dishes to gather scientific evidence like electromagnetic waves, in order to search for life on other planets. For a number of years, these probes were funded by the U.S. government, but lately the funding has been taken on by private sources. Several scientists have spent their lives trying to establish links between strange phenomena and the existence of life in outer space. Principal among them are Carl Sagan and Frank Drake. Carl Sagan theorized that alien life such as bacteria exist not only in our planet but throughout the universe. He also insisted that it is impossible that no other intelligent life exists in the universe other than on Earth. Frank Drake, the founder of SETI, has devoted his life to establish the presence of aliens. He is famous for coming up with the Drake or Green Bank equation. The Drake equation, can apparently help determine the number of intelligent civilizations that exist in our galaxy, Milky Way. It uses a number of factors to determine results, the rate of formation of stars, the average number of planets that have life, planets that will develop intelligent life, etc. The Drake equation was an attempt to quantify factors that were previously undetermined. There have been several other research projects to establish that there are such things as aliens. More important of them are the several space missions, which have tried to establish life on Mars due to evidence of methane in the atmosphere and the mission to establish life on moon, due to reported presence of water. Of course, there are also other factors that need to be taken into consideration like alien abduction stories that have been reported by several people. In fact in a study carried out by Harvard in 2003, seven of 10 hypnotized abductees, described test done on them by their alien captors. Real alien sightings are also events that cannot be dismissed as overactive imagination
