Once upon a time,
The professor of a university challenged his students
with this question : "Did God create everything that
exists?" A student answered bravely: "Yes, He did".
The professor then asked, "If God created everything
then He created evil. Since evil exist, so God is
evil". The student respond to that statement causing
the professor to conclude that he had "proven" that
"Belief in God" was a fairy tale and therefore
worthless.

Another student raised his hand and asked the
professor, "May I pose a question?" "Of course,"
answered the professor. The young student stood up
and asked: "Professor, does cold exist?" The professor
answered, "What kind of question is that? Of course
cold exists ....... haven't you ever been cold?". The
young student answered, "In fact Sir, cold does not
exist. According to the laws of Physics, what we
consider cold, in fact is the absence of heat.
Anything can be studied as long as it transmits energy
(heat). Absolute zero is the total absence of heat,
but cold does not exist. What we have done is to
create a term to describe how we feel if we don't have
body heat or we are not hot"."And does dark exist"? he
continued. The professor answered, "Of course". This
time the student responded, "Again, you're wrong, Sir.
Darkness does not exist either. Darkness is, in fact
simple, the absence of light. Light can be studied,
darkness cannot. Darkness cannot be broken down. A
simple ray of light tears the darkness and illuminates
the surface where the light beam finishes. Dark is a
term that we humans have created to describe what
happens when there's lack of light".

Finally, the student asked the professor, " Sir, does
evil exist?' The professor replied: "Of course it
exists, as I mentioned at the beginning, we see
violations, crimes and violence anywhere in the world
and those things are evil". The student responded,
"Sir, evil does not exist. Just as in the previous
cases, evil is a term in which man has created to
describe the result of the absence of God's presence
in the hearts of men.

After this, the professor bowed down his head and
didn't answer back. The young man's name was Albert
Einstein.
