Can someone explain to me whether witchcraft is credible?

This is absolutely unbelievable. The so-called witchcraft is just a seemingly incredible phenomenon made by using some simple physical or chemical reactions combined with some cover-ups. I don't know if you have seen the CCTV 10 column (you can understand from watching this program often that many seemingly strange phenomena in life are actually just simple scientific truths). A while ago, there was a special week about so-called exorcism. There are many malicious people who claim to be masters or witches to treat people and eliminate disasters. In fact, they just use some scientific phenomena that you don't know to deceive people. They all cheated the victim of his money and ran away.
