Meaning

As humans, we find it very difficult to live with the unknown, whatever we discover we try to attach a meaning to it even if sometimes the meaning is not valid, this is because the brain itself cannot comprehend raw information(data), data that is unprocessed and doesn't makes sense, so a kind of mapping occurs between ideas and meaning, if a meaning does not exists, instead of assigning NULL to it, it rather randomly selects a meaning(mostly the obvious which is not always True) and maps it to the idea/concept.

For instance, one lived his whole life believing that Teleportation is merely a fiction and there is no way it can become a reality. Once that idea have taken hold in the brain, grows root and its well comprehended it is almost impossible to map it to another different meaning. Now, if this person happens to witness a person Teleport, because that meaning to an original idea that has a meaning and taken hold of the brain exists, the brain will have no way to replace the original idea with the new, then it finds an existing idea with a meaning lets say idea: superior being exist, and meaning: hes capable of making miracles happen, then we the person says this is a miracle (this is an original idea of believing in the superior being without actually seeing "Faith").

With this idea, he can convince almost anyone "its a miracle", and since one person believes that idea, he can easily spread it like a disease to everyone, just by convincing those who trust him. Believe me we all have people we trust and can tell anything, and we all are connected, so this is possibly going to go viral.
