Argument:Does God exist?

A man went to a barber shop to have his hair and his beard cut as always.
  He started to have a good conversation with the barber who attended him.
  They talked about so many things and various subjects.
  Suddenly, they touched the subject of God.

  The barber said: "Look man, I don't believe that God exists as you say so."
  "Why do you say that?" - asked the client. Well, it's so easy, you just have
  to go out in the street to realize that God does not exist.
  Oh, tell me, if God existed, would there be so many sick people?
  Would there be abandoned children?
  If God existed, there would be no suffering nor pain. I can't
  think of a God who permits all of these things."

  The client stopped for a moment thinking but he didn't want to respond so
  as to prevent an argument. The barber finished his job and the client went
  out of the shop.
  Just after he left the barber shop he saw a man in the street with a long hair
  and beard (it seems that it had been a long time since he had his cut and he
  looked so untidy).

  Then the client again entered the barber shop and he said to the barber:
  You know what? Barbers do not exist." "How come they don't exist?"-asked the
  barber.
  "Well I am here and I am a barber."
  "No!" - the client exclaimed.
  "They don't exist because if they did there would be no people with long
  hair and beard like that man who walks in the street."
  "Ah, barbers do exist, what happens is that people do not come to me."

  "Exactly!"- affirmed the client. "That's exactly the point. God does exist, what
  happens is people don't go to Him and do not look for Him that's why there's
  so much pain and suffering in the world."
