Well the O.P was always going to create an explosive thread. Yet it's basically a matter of FAITH & BELIEF, for those who believe in God, no proof/ explanation is necessary. For those that don't believe in God, no proof/explanation is not a satisfactory answer. However maybe the trick is not to take things so seriously and try to get along?

p.s if anyone is really interested in "proof of Gods existence" may I reccomend you read Belottis, 47 volumes of " History of Catholicism" It not cheap but if you are down to your last £547.17pence, buy it , you won't regret it.
