What do you have to sell your soul the devil?

There is no such thing as selling one's soul to the devil. The concept of making a deal with the devil is a myth or a metaphor that has been used in folklore, literature, and popular culture to represent the idea of making a Faustian bargain, where a person gains something they desire in exchange for something of great value or significance. However, in reality, there is no evidence or basis to suggest that such a transaction is possible.
