God exists...

Teacher: Did God create everything?
Student: Yes.
Teacher: If so, then God created evil. Therefore, God is evil.

Suddenly 1 student stood up...
Student:  Ma'am, does COLD exist?
Teacher: Yes it does.
Student: Actually Ma'am, it doesn't. According to the laws of physics, COLD is simply the absence of HEAT...
              Now, does DARK exist, Ma'am?
Teacher: Of course it does.
Student: DARK doesn't exist...It is only the absence of LIGHT...
             Just like EVIL, it is only the absence of GOD in a man's heart...

Teacher left speechless...
