Professor: Did God create everything?
Student 1: Yes, Sir !
Professor: Sure ?
Student 1: Yes, Sir !
Professor: Well then, evil exists, and hence God created evil.
(Student 1 didnot know what to say and the Professor continued.))
Professor: Since deeds define the doer, God is evil.
(Student 1 found the entire structure of his belief in God crashing down)
Student 2: Professor, does darkness exist?
Professor: Of course is does.
Student 2: I am sorry you are wrong. What exists is light. Darkness is just the absence of light.
(The Professor was dazed and started thinking how to counter this.)
Student 2: Professor, does cold exist?
Professor: Hmmm? well yes it does.
Student 2: I am sorry you are again wrong. What exists is heat. Cold is just the absence of heat.
(Professor was now feeling very aukward in front of the whole class.)
Student 2: Now, Professor,  does evil exist?
(Professor was now irritated)
Professor: I told you just now that evil does exist. You see it every where in terms of crime and voilence.
Student 2: You certainly said that evil exist, but you were again wrong. Evil does not exist.
                   It is just the absence of the love for God in one's heart. It is just like the feeling
                   of cold when there is no heat, or the darkness when there is no light.
The Student 2 was Albert Einstein
