The UFO, also known as Flying Objects not identified, are devices which can not be recognized. Su Its origin is clarified either after their study.

One of the phenomena being studied to see if it is true the appearance of these objects is the sighting, through photos and videos and testimonies by people.

History

The phenomenon ovni is a term that appeared in the second half of the twentieth century. Despite this, many scholars see in the Bible interpretations of sightings of these vessels.

During the eighteenth and nineteenth centuries, there were also several comments from flying objects in different cities around the world such as in Copiapo Chile, or Ciudad Real Madrid.

The first sighting occurred in 1947 in USA Kenneth Arnold noted from his plane to fly multiple objects with triangles at high speed. Since that day many celebrate the day of San Kenneth Arnold.

Roswell Incident

In 1947 also took place in the so-called Roswell Incident, which was observed as a ovni had crashed in New Mexico and the American army had captured several creatures from another galaxy.

With the passage of time and after much research showed that everything had been a farce, because of the remains found ovni responded to an American military ship and the aliens were merely puppets of evidence.

Ufología

It is a science that studies UFO through certain materials such as photographs, videos, testimonials from individuals or reports radars.

Many sectors outside the ufología not treat it as science, because ufólogos not sure if what they are studying exists or not, only have visual and oral testimony of these phenomena.

Scholars believe that the work they can get to play ufólogos can also fulfill other sciences. For example, the UFO can be studied by engineers and biology to extraterrestrials.
