Faith or religion will never be fact. You can never prove "he" or whatever exists, but I understand why people believe in a god. It's somewhere to turn for help, comfort, for a reason to live and otherwise. It's human tendancy to look for comfort when in a bad situation, and thats what a god gives them. It also explains the unexplainable. So SOMEDAY christianty, islam, and jeudeism will all fade out, but until then, more power to those who have faith.
1. Confident belief in the truth, value, or trustworthiness of a person, idea, or thing.
