Do alians really exist???

Do aliens exist? This question has baffled humans for centuries.

Most of us are reserving judgment on whether there is intelligent life on other planets; we haven’t even found bacteria yet, much less a race of aliens with Internet service and takeout food.

But there are some researchers and scientist who believe in existence of aliens. Some description that provided by those scientist is explained below;

From Roswell to Suffolk's Rendlesham Forest, these are the sightings which UFO hunters have hailed as proof of extra-terrestrial life.The Roswell UFO incident is a world-renowned conspiracy theory about the existence of aliens. In the summer of 1947, a farmer discovered unidentifiable debris in his sheep fields just outside Roswell, New Mexico. A local Air Force base claimed the debris came from a crashed hot air balloon, but many people reckon it's really the remains of a flying saucer.

Dubbed the "British Roswell", a similar incident happened in Rendlesham Forest in 1980.
On December 26, Military personnel from RAF Bentwaters and RAF Woodbridge, in Suffolk, saw strange lights in a nearby forest - and three of them were sent out to investigate.Two of them encountered a small, triangular shaped craft - which they later drew images of.One man, Jim Penniston, got close enough to touch the side of the object.Two nights later, Deputy Base Commander Lieutenant Colonel Charles Halt and his team also encountered the UFO - and were left baffled by the entire experience.

In October last year, scientists offered a new theory to explain why a distant star called KIC 8462852, or Tabby’s Star, was displaying a bizarre “blinking” behavior which caused its light to dim periodically. One researcher made the serious suggestion that the light was being blocked by a huge object called a Dyson Sphere – a theoretical structure which could be built around a star in order to harvest its energy. Some scientists believe Europa, which is about the size of Earth’s moon, has an ocean hidden beneath its frozen crust. If the predictions turn out to be correct, this could be a great place to look for alien organisms.
