Oh, really? Okay, so you want to point to people's linguistic dispositions as proof that objective morality is real. Fine. But even if we grant this, it isn't clear that you couldn't equally argue that morality just comes from nature or that it's built onto the very fabric of reality as a necessary feature. Maybe God isn't required for objective morality because maybe objective morality just comes from the way things are. But I'm hesitant to grant even this much since it is a largely unsupported thesis, but in terms of parsimony it's equally, if not more plausible, and removes unnecessary explanatory debt.
