A miracle is an event believed to be caused by interposition of divine intervention by a supernatural being in the universe by which the ordinary operation of Nature is overruled, suspended, or modified. The term is derived from Latin word miraculum meaning "something wonderful".

Many folktales, religious texts, and people claim various events they refer to as "miraculous". There are no scientifically confirmed occurrences of miracles. Miracles are not subject to controlled experimentation and the mechanism of occurrence not recognized by the scientific community. One aspect of some miracles which makes them almost impossible to verify is the fact that they are often manifested only to small groups of individuals, and sometimes centuries ago.

People in different cultures have substantially different definitions of the word "miracle". Even within a specific religion there is often more than one of the term.

Sometimes the term "miracle" may refer to the action of a supernatural being that is not a god. Thus, the term "divine intervention", by contrast, would refer specifically to the direct involvement of a deity.

In casual usage, "miracle" may also refer to any statistically unlikely but beneficial event, (such as the survival of a natural disaster) or even which regarded as "wonderful" regardless of its likelihood, such as birth. Other miracles might be: survival of a fatal illness, escaping a life threatening situation or 'beating the odds'.

Miracles as supernatural acts

In this view, a miracle is a violation of normal laws of nature by some supernatural entity. Some scientist-theologians like Polkinghorne suggest that miracles are not violations of the laws of nature but "exploration of a new regime of physical experience".

The logic behind an event being deemed a miracle varies significantly. Often a religious text, such as the Bible or Quran, states that a miracle occurred, and believers accept this as a fact. However, C.S. Lewis noted that one cannot believe a miracle occurred if one had already drawn a conclusion in one's mind that miracles are not possible at all. He cites the example of a woman he knew who had seen a ghost, who had discounted her experience; claiming it to be some sort of hallucination (because she did not believe in ghosts).

Many conservative religious believers hold that in the absence of a plausible, parsimonious scientific theory, the best explanation for these events is that they were performed by a supernatural being, and cite this as evidence for the existence of a god or gods. However, Richard Dawkins criticises this kind of thinking as a subversion of Occam's Razor. Some adherents of monotheistic religions assert that miracles, if established, are evidence for the existence of an omnipotent, omniscient, and benevolent god.
