Does god exist?

This has a thought provoking message no
matter how you believe. Does evil exist?
A university professor challenged his students
with this question. Did God create everything
that exists?
One 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 himself
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. Everybody and every object is
susceptible to study when it has or transmits
energy. and heat is what makes a body of
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 too little 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
everyday. 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, that exist just as does light and heat.
Evil is the result of what happens when man
does not have God' s love present in his 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 young man' s name?
