Actually it's star-stuff. We are made of the very same elements that make up the sun, the earth, and the stars. And as Whitman said, "Ev'ry atom belongs to me/As good belongs to you." And given the way our bodies are recycled after death, we all probably have a few atoms in us that once belonged to Genghis Khan, Christ or Mohammad.
But sorry--no Elvis yet! It hasn't been long enough
