It strikes me that it is quite valid to believe that an intelligent reasonable being was able to create the universe from nothing. Further more, it I can't see anything unreasonable or illogical in believing that this being would incarnate himself into a living human being. You may not believe it, you may not like it, but you have to accept that it is possible. Likewise it is no dimunition to someones intelligence to believe in this. Instead we should remember that some of the best brains have been, and are, practising Christians.
So if there any militant athiests out there, come on, tell me how is my faith unreasonable?
