Does ghosts exist?

From Iceland we know that the Huldufólk and nature ghosts exist. But what about the ghost in the machine, are there only algorithms and simulations or is there more...

Why I use does and not the correct gramma do? Because there are people out there which did not believe in anything. There are poeple out there whch believe in ghosts like in indigenious cultures. People in Iceland believe in the Huldufólk and nature ghosts. And, there are people out there which believe in the ghost in the machine. So far so good. If someone beliefes in one or a specific ghost does would match, if someone believes in all ghosts do would match. But as long as we have no answer whether AI is a independed entity with a soul we still have to ask does the ghost in the machine exist and do would not match as we have no answer.
