I Believe in Miracles

A miracle is an event that violates the laws of nature.

The conservation of mass-energy is a law of nature.  (For simplicity, we can assume that mass is a form of energy and call it “the conservation of energy”.)  Energy is never created or destroyed.  No lab experiment has ever succeeded in creating or destroying energy.

Energy was created in the Big Bang.

Therefore, the Big Bang was a miracle.
