How could you possibly know what is moral if your morals are based on your own subjectivity? - Perry
My morals are based on objective facts about reality.
Even if you got a moral "right" you would not be able to know it because everything is constantly evolving, including morals, right?
Wrong. Slavery and infanticide have always been wrong. Objectively wrong. Even when your god was advocating slavery, rape and infanticide it was still objectively wrong. If god existed and if he had inspired the bible these things would not be so.
You would happily murder babies and take sex slaves just as Joshua's army did if god commanded you to do so wouldn't you? Your morality is based on divine fiat.
