Another counter-argument is Occam's razor, which can be used to argue that God is unnecessary to explain miracles for which natural explanations can be found. In his documentary The Root of All Evil?, British evolutionary biologist Richard Dawkins utilises this argument when examining the supposed miracles in Lourdes, France. According to Catholic theology, supernatural cures occur in the area, but Dawkins expresses doubts as to their divine nature, noting that all the recorded cures comprise diseases which may have healed by themselves without the need for divine intervention.
