The university professor challenged his students with this 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 was quite pleased with him self and boasted to the students that he had proven once more that the Christian 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 degrees F) is the total absence 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."
