My flatmates are MEGA christain and I am a non believer. We have had massive discussions over this. The one miracle which will escape me is that there is existance,energy, anything. To this they say that god is responsible. 2 of them believe the book of fibs because they are nuts but the other almost trained to be a priest and makes the most sense with his talk on feelings.
I go down the evolution route etc etc, the book is a moral template, much like a government etc so I definately do not believe in that etc, but the one big miracle, thats a good un.
It's tough to argue. So you first have to say - what is god?
