Picture with me for a moment some soggy, Middle Eastern men on an ancient boat in the middle of the night. Their arms are slick with seaspray, jellied from bailing water and rowing against the wind.
They’ll argue about who saw it first, but unmistakably, something was silhouetted on the crests and peaks of the waves. And it sure looked a whole lot like a person.
But because people can’t really float upright on water–as fishermen, they’re confident of this–their minds vault to the supernatural: A ghost.
