A university professor challenged his students with a question, "Did God create everything that exists?"

A student bravely replied, "Yes, he did!"

"God created everything?" the professor asked.

"Yes sir," the student replied.

The professor answered, "If God created everything, then God created evil, since evil exists, and according to the principal that our works define who we are, then God is evil."

The student became quiet before such an answer. The professor, quite pleased with himself, boasted to the students that he had proven once more that ... faith was a myth.

Another student raised his hand and said, "Can I ask you a question, professor?"

"Of course," replied the professor.

The student stood up and asked, "Professor, does cold exist?"

"What kind of question is this? Of course it exists. Have you never been cold?" The students snickered at the young man's question.

The young man replied, "In fact sir, cold does not exist. According to the laws of physics, what we consider cold is in reality the absence of heat. Every body or object is susceptible to study when it has or transmits energy, and heat is what makes a body or matter have or transmit energy. Absolute zero (-460° F) is the total abscence of heat; all matter becomes inert and incapable of reaction at that temperature. Cold does not exist. We have created this word to describe how we feel if we have no heat."

The student continued, "Professor, does darkness exist?"

The professor responded, "Of course it does."

The student replied, "Once again you are wrong, sir; darkness does not exist either. Darkness is in reality the absence of light. Light we can study, but not darkness. In fact we can use Newton's prism to break white light into many colors and study the various wavelengths of each color. You cannot measure darkness. A simple ray of light can break into a world of darkness and illuminate it. How can you know how dark a certain space is? You measure the amount of light present. Isn't this correct? Darkness is a term used by man to describe what happens when there is no light present."

Finally the young man asked the professor, "Sir, does evil exist?"

Now uncertain, the professor responded, "Of course, as I have already said. We see it every day. It is in the daily example of man's inhumanity to man. It is in the multitude of crime and violence everywhere in the world. These manifestations are nothing else but evil."

To this the student replied, "Evil does not exist sir, or at least it does not exist unto itself. Evil is simply the absence of God. It is just like darkness and cold, a word that man has created to describe the absence of God. God did not create evil. Evil is not like faith or love or light or heat that do exist. Evil is the result of what happens when human beings do not have God's love present in their heart. It's like the cold that comes when there is no heat or the darkness that comes when there is no light."

The professor sat down.

The student's name - Albert Einstein.
