That's a bit presumptious.
If there is no God, then why is there a premium set on ‘good’?
What is more impressive:
1) Someone who follows a strong moral code. who believes that they, Mother Theresa, Adolph Hitler, and everyone else will be the same place - nowhere - after they die,
2)Someone who follows a strong moral code because they believethat they will be punished or rewarded for it after death?
A set of moral standards and ethics doesn't require a deity. People blindly assert that because it makes them feel better (and superior), however.
Who cares about your man-made ‘moral (small ‘m’) code’?
The ‘morals’ today say that it is fine a for men to have sex together, that it is ok to kill and unborn child and that it is ok to lie, ad nauseum.
Without a fixed, set-in stone Moral code, you are at the mercy of man, not a good place to be, ask the Germans in WW2, or any unborn abortion victim.
