Remember the story of Elijah and Baal's priests? well, you can do the same test now as well; put a sick patient on a bed, get those christians to pray for the sick person to heal. Can't do it? then let science/doctor/modern medicine try. The latter will heal the sick person!
then it will be science and modern technology's turn that should slay the superstitious religions for falsehood!
