quote:The difficulty appears to lie in the assertion by believers that we can't know what right and wrong is without there being a god to tell us. The question is why not?
The question is really the reverse: Wouldn't humans behave more morally if religion never had been invented?
Face it: good people may behave well and bad people may behave badly, but to persuade both good people and bad people to commit really heinous deeds it requires religious belief (or some other odious ideology like that of Mao or Hitler) and true believers to tell them to do these deeds.
There is no "universal morality that flows from God". In fact, the painstaking process of humanity figuring out what is moral and what is not (remember, not long ago almost everyone - including Bary Obama! - thought that marriage between two people of the same sex was immoral) has been only made more difficult by that human invention called religion.
