Actually, this is the statement that's true:
4. Steve-b should immediately invest in a logic course at his local community college.
Now, part of the reason you got that wrong was because you misread what I meant; perhaps I could have put it better. The atheist may not recognize the lawgiving God. He may completely believe that his morals have no connection to any religion. But the bottom line is that his morality has no underlying justification at all.
Let's say that the atheist says "It's morally right for me to give blood and morally wrong for me to steal." Well, why? Why isn't it OK to look out for number one? Why is there any obligation to society?
That kinda sorta suggests the answer (you believe that Hammurabi’s Babylonian gods were, in fact, real), but isn’t clear. Can you work on that?
You listen to the first guy and ignore the second guy.
Well, why? Both of them equally invoke the authority of God, so God cancels out as a basis for decision. Why isn't it OK to listen to the other guy instead?
