If there is no god, then atheist Bob is not better than god.
So, the Bob does not exist.
God is supreme Being. So, non-existent one means, that Bob is non-existent.
Zombie/vampire is there but is dead and non-existent. Presence and existence are not the same.
I was just wondering if anyone of you thought there were any religions that are inherently in tune with one of those 3 concepts? Taoism popped into my head to a certain extent but I'm not sure how far you could legitimately take that.
