Yeah, they're a great guide on how to treat your slaves, how many birds should one sacrifice when his wife is having her period, how much money should one demand when someone beats his wife so much that she has an abortion. Truly "social values".
Social values didn’t originate out of thin air. Abrahmic Religions actually introduced them. There is a God.
Those actually two separate assertions.
The first one could be true, but that 1) doesn't give credence to the beliefs 2) is not a good reason to have social values now, given the existence of more humanistic and less magical-thinking mechanisms to propose and enforce social values (secular humanism, for one).
The second one is unproven and, depending on the god alluded, unprovable, and such entities are not worthy of belief until such a time where their existence is unequivocally proven, presenting objective, material, reproducible evidence that skeptics can examine, and that can be considered valid both via the scientific method and in a court of law.
