Wondering why this "why is it more bilieveable there is a god, but not a good man/woman"?
Good point. We've all met "bad" men and women, howvever in many cases the idea of what is "bad" varies from one culture to another. I think it is possible for a person to be "good" within the context of their own culture, but even that is still pretty rare.
There are plenty of good men and women but they may be scared away by bad spelling....
