No physicist has ever 'seen' an electron. Yet, all physicists believe in the existence of electrons. An intelligent but superstitious man advances this analogy to argue that ‘ghosts’ exist even though no one has ‘seen’ one. How will you refute his argument?

Solution

No Physicist has ever seen an electron. But, there is so much of evidence that establishes the existence of electrons. Atomic power plants, atomic bomb, etc. give the authenticated proof for the existence of atoms in nature. Whereas, on the contrary there is hardly any direct or indirect evidence on the existence of ghosts in this world. The stories of ghosts still revolves around myth stories.
