There are things that science is still too raw or not advance enough to justify.
If one person can use his brain 1% more than normal people, its is already considered genius / savant. Imagine those with a lot more. I believe such supernatural thing exist but not in a way that we want to make believe like we seen in those hollywood movies. Can you explain Qi ?

If I may put in intelligible meaning, sorcery doesn't exist except in our imagination, fantasy and illusion. There's a part in our brain that controlled the intensity of hallucination by an individual. Almost all people who believe in sorcery are superstitious, such relationship between both are worth scrutinized meticulously.
