Magic is an honest lie. People know you are lying, but you have made it clear that it is a trick. Just whether you can see it transparently.
The second half of this video shows you how it is actually done.
Not everyone is so forthcoming about how a magic is done. That's fine, as long as it is an honest lie.
The problem is there are people who lie, also for a living, but in a totally different way.
Religious healing has never worked. Watch how father Jonathan still emphasises the healing power of god. How much hypocrisy is showner?
