Do psychics really exist?

It's just that the characters in novels or TV plays are all made up by the director. There is no soul in the world, so there is no psychic.

In recent years, because of the development of science, more and more people find it unrealistic to communicate with the deceased. But since some people claim to have this function, countless people will spend a lot of money to buy this service. So someone once said that the most profitable profession is actually a psychic.
