A professor challenged a student to prove that God created everything, including evil. The student responded that evil does not truly exist. He asked if cold exists - it is actually the absence of heat. Darkness too is the absence of light. Similarly, evil is the absence of God, love, humanity and faith in people's hearts. It is the absence, not the presence of these good things, that leads to what is termed "evil". The professor had no response to this insightful explanation.
