Superstitions

So many people have superstitions that I don't agree with, superstitions are the belief and magical effect, for example when people saw a black cat past in front of then in the night they think that have bad luck and many people don't know why, this is because when inexplicable thing happen to you and you want to feel in control of something that you don't understand. They are part of the cultural heritage of the people, but that are just myths and not think it's real that an passed from generation to generation that I don't agree with.
