A professor tried to prove to students that faith was a myth by asking if God created everything, including evil. A student responded that cold and darkness do not truly exist - cold is the absence of heat and darkness the absence of light. He then asked the professor if evil exists, to which evil is the absence of God, love, humanity, and faith in people's hearts. Just as cold is the absence of heat and darkness the absence of light, evil is the absence of qualities like love that do exist. The student who responded was Albert Einstein.
