I have no idea what he's talking about...I guess he's trying to use that old 'if there was no God there would be no good' logic. Actually, if you think about it, if we were all murderers and rapists that would be considered 'good' because what is considered good and bad are set by human morals. If humans had not decided that the race must survive and thus, murdering for no reason is bad, we wouldn't be here or we'd be killers who are perfectly intent. But now that we're here, it is no matter, because if it hadn't happen we wouldn't be here to argue about it.

If that argument was your original intention, of course.
