Why do people believe in ghosts?

Ghosts have never been proven to exist, so it is intellectually responsible and prudent to conclude they do not exist.

In order to make sense of our world, we must use the scientific method, not spooky stories, opinions, hoaxes or outright lies by people who need attention or need to feel special. Other believers may be uneducated, superstitious or just too young and naive.

The Scientific method refers to a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. To be termed scientific, a method of inquiry must be based on gathering observable, empirical and measurable evidence subject to specific principles of reasoning. A scientific method consists of the collection of data through observation and experimentation, and the formulation and testing of hypotheses.

Scientific researchers propose hypotheses as explanations of phenomena, and design experimental studies to test these hypotheses. These steps must be repeatable in order to dependably predict any future results. Theories that encompass wider domains of inquiry may bind many independently derived hypotheses together in a coherent, supportive structure. This in turn may help form new hypotheses or place groups of hypotheses into context.

Among other facets shared by the various fields of inquiry is the conviction that the process must be objective to reduce biased interpretations of the results. Another basic expectation is to document, archive and share all data and methodology so they are available for careful scrutiny by other scientists, thereby allowing other researchers the opportunity to verify results by attempting to reproduce them. This practice, called full disclosure, also allows statistical measures of the reliability of these data to be established.

In summation: For something to exist it has to be proven. This is how we escaped the dark ages - using reason and logic. So, for now, ghosts do not exist.

Another "Answer"

People believe in ghosts because they might have feelings that spirits are in their own home......I'm terrified of them.....

Other answer:

I believe in ghosts but are scared of them. People Believe in ghosts because they read and see things about them that builds up their belief of ghosts. So, when they start seeing and hearing things in the night, they think it is a ghost.

Many people still believe in ghosts because they fear death. They are afraid of dying themselves, and they are saddened when others who are close to them have died. The idea of ghosts is a psychological coping mechanism, a relief in the form of a false idea that a "spirit" is capable of transcending death.

Humans, like most higher animals, fear the unknown. But death is nothing to fear. We were all dead before we were born, and when you're dead you won't even know it!
