Did God create Evil?

One day, a professor of a university decided to defy his pupils.
He asked: "Did God create everything that exists?"
A student answer bravely: "Yes, God did"
"Everything?" asked the professor.
"Yes, everything" was the answer of the student.
"In this case, God also created evil, correct? Because evil exists" said the professor
To that, the student had no answer and remained in silence.
The professor was delighted at the opportunity to prove one more time that "Faith" was only a myth.
Suddenly, another student raised his hand and asked: "May I ask you a question, professor?"
"Of course" professor replied.
"Does cold exist?" the student asked.
"Of course. Did you never feel cold?" the professor replied
"Actually, sir, cold does not exist. According to studies in Physics, cold is the total and complete absence of heat. An object can only be studied if it ha and transmits energy and it is the heat of an object that transmits it's energy. Without heat, the objects are inert, incapable to react. But cold does not exist. We created the term of cold to explain the lack of heat."
"And darkness?", continues the student.
"It exists", replied the professor.
"Again, you'r wrong sir, darkness is the total absence of light. You can studied light and brightness, but not the darkness. The prism of Nichols shows the variety of different colors in which the light can be decomposed according to the longitude of the waves. Darkness is the term we created to explain the absence of light."
And finally, the student asked: "And evil, sir, does evil exist?God did not create evil. Evil is the absence of God in people's heart, if the absence of love, humanity and faith. Love and faith are like heat and light. They exist. Their absence lead to evil".
Now it was the professor's turn to remain silent.

And the name of the student is "ALBERT EINSTEIN" (Jews)
