Personally I don't see myself as needing to believe in an eternal punishment system, or even to be frightened of breaking human laws as the only motivations to govern my own behaviour.
I know the arguments that certain groups use as to why humans are unable to govern their own behaviour but I tend to disagree with those arguments. I know many people who choose not to believe in a creator being who behave far better than many others who do believe in a creator being.

I personally prefer to keep my own beliefs to myself and the owners of these forums would also prefer that religion is not discussed here. That is mainly because the internet is a world-wide medium and as such, religious discussions can be very vollatile.
