Evil exists?

During a conference with several university, a professor at the University of Berlin atheist, challenged his students with this question: - God made everything that exists?
A student bravely replied
- "Yes, He created!" - God created everything, right? - Yes, sir, - replied the young man.
The teacher replied: - If God made everything, then God created evil, since evil exists, and considering that our actions are a reflection of ourselves, then God is evil.
The student was silent before such an answer and the teacher, happy, boasted had proven once more that faith was a myth.
Another student raised his hand and said: - I ask you a question professor?
- No doubt, replied the teacher.
The student stood up and asked: - Teacher, does cold exist?
- What kind of question is that? Of course there is, you happen never been cold?
The boy replied: - Actually, 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 can be studied when it has or transmits energy, and heat is not the cold that makes such a body have or transmit energy. Absolute zero is the total absence of heat; all matter becomes inert and incapable of reaction, but cold does not exist. We created this word to describe how we feel if we have no heat.
- And the teacher darkness, is there? - Continued the student.
The teacher replied:
- Of course, yes.
The student replied:
- Again you are wrong, darkness does not exist either. Darkness is in reality the absence of light. Light we can study, but not darkness. The prism Newton decomposes white light into different colors that compose, with their different wavelengths. The darkness does not. A simple ray of light tears the darkness and illuminates the surface that the light touches. How do you determine how dark a certain space is? You measure the amount of light present, is not it? Darkness is a term used by man to describe what happens when there is no light present.
Finally, the young man asked the teacher:
- Tell me, teacher, does evil exist?
He replied: - Of course there is. As I said at the beginning of class, we see thefts, crimes and violence daily in all parts of the world, these things are evil.
Then the student replied: - Evil does not exist, sir, or at least does not exist by itself. Evil is simply the absence of God, the absence of Good. It is, as in previous cases, a term that man has created to describe the absence of God. God did not create evil. It's not like faith or love, that exist as there is the light and the heat. Evil is the result that humanity does not have God present in their hearts. It's like the cold that comes when there is no heat or the darkness that comes when there is no light. "
By the 1900s, this young man received a standing ovation, and the teacher just nodded remaining silent ...
Immediately the director went to that young man and asked what was his name?
And he said: ALBERT EINSTEIN
