There are some people who believes in things which are outside the field of science and even it has been scientifically proven fictitious by the science.
This is because that nobody has given solid evidence that paranormal beliefs such as ghost, aliens and UFOs exists. The question arises that why paranormal beliefs are so common and popular among people when it lacks solid evidences? One of the main reason is media which forces the individual to believe in these paranormal activities. Many horror movies nowadays claims that these incidents are based on real life events which further increases the curiosity of the peoples. According to Britt(2008) that the human constantly tries to figure out things and when the brain is unable to do so, it cames up with odd or unrealistic explanations.
