What is Alien? An Alien or extraterrestrial being is life outside of our world. So, it is a living being, in any form, which exists on other planets or in any place in our universe. We must not confuse Aliens with those fictional characters in Hollywood movies because if today some people are still short-minded by laughing at you when you talk on Alien, it is simply because Hollywood movies have brainwashed them. An extraterrestrial life can be a form of a bacteria, microbe, humanoid etc. We do not know as we have never met them!
The Search for Extraterrestrial Life (SETI), which was founded by some brilliant astronomers like Carl Sagan after the 1960s, has the mission to communicate with Alien through sending signals. Several signals have been sent such as the Arecibo message which is composed a description of human being, the planet we live, DNA code and much more. The message will take thousands of years to reach its destination and will take the same amount of years to come back to us. SETI is implementing more new advanced equipment to send signals. A source, the responsible person of SETI revealed that perhaps in the next 20 years, we will already have our first contact.
This universe is so huge to not believe an existence of an extraterrestrial life. We have detected hundreds of planets which are similar to us and may contain life such as Kepler and Gliese. The problem, they are too far away to reach. Most Astrophysicists and Physicists believe there is a high possibility of life in the universe apart on earth. Stephen Hawking pointed that it will be better if human beings do not make any contact with Aliens as it can be a danger but it is too late now, we have already sent signals to communicate with them!
Other factors that can support Aliens may have visited us are conspiracies! Have you watched the documentary Ancient Aliens? It clearly shows the evidences. You may not believe in them but in another perspective, it can be true. The evidences are so strong! Moreover, we have conspiracies linked to the crash of Roswell in the 1940s, Area 51 where Bob Lazar, a government scientist who worked there claimed experiments are being done with the help of extraterrestrial beings. An astronaut, Edgar Mitchell believes NASA is hiding the truth. We have also the cases of Phoenix Lights and the Unidentified Flying Object (UFO) in China where a Chinese airport has to shut down. Several UFO sightings have been reported. The list of cases goes on…
Conspiracy theorists go further to state some governments have contacted Alien beings but they are keeping this as a secret. They are working with Aliens in military purposes. Area 51 is often subjected to this conspiracy! There are certain who believe Aliens have abducted human beings. The increase in UFO sightings is persistent. Some conspiracy theorists associate the construction of Pyramids on Aliens. Do not forget, ancient civilizations like the Mayans believed in an extraterrestrial life.
We ask one thing, have we visited before? You decide!
