Belief and Opinion

What is the difference between a belief and an opinion? A belief is defined as an opinion, a conviction, and confidence in the truth of something without absolute proof. Words such as faith are also associated with belief. An opinion is defined, as a judgment not substantiate by enough support to yield certainty, a personal view or attitude, or professional judgment. One may extend beliefs about opinions or opinions about beliefs, and one may extend opinions about opinions. One may also extend beliefs about beliefs. But how can one appraise the differences when they are being used? Is there truly a difference?

If one believes in fairies, and another opines, such belief is false, would that opinion have changed the nature of the interaction between the concept of belief or opinion? If the other said, " I do not believe in fairies" is he saying he does not opine that fairies exist? Is there even a slight difference in the usage of opinion and belief? Let us see how the definition applies.

If an opinion is a judgment not substantiated by enough support to yield certainty, in the application of the concept of opinion, there should be insufficient support for the existence of fairies, and assuming that archeology has not discovered the remains of fairies' skeletons, let us assume the application of the concept of opinion is correct, maybe. If the other said "I do not believe in fairies" and the definition of belief is an opinion, a conviction, and confidence in the truth of something without absolute proof, with the meanings being almost identical, apparently the same concepts are being applied.

Both concepts of belief and opinion are driven by the factor of insufficient evidence. Seemingly, there is no clear distinction between the two supposed competing concepts. By saying, "I am of the opinion that fairies do not exists", apparently the other is also saying, " I don't believe in your belief." Belief and opinion do not seem to be quite clearly distinguished in this scenario, as the concepts of both apply correctly thus far. But what becomes of the nature of the concepts in the following scenario.
