The Ma'atian ethics, so-called, are seen by many historians as a foundation of societal longevity. I have a beautiful painted Egyptian statute of Ma'at on my bookshelf and the various codes attributed to her worship not only promoted civility, but justice. If followed, those codes not only helped provide for the common defense, but helped ensure domestic tranquility. These are traits put into the hearts of men by God and are recognized as being honorable and virtuous attributes far removed from instinct. Cats all over the world lick themselves the same way without being taught, but instinct can't explain ingrained moral behavior.
Slavery. NOT servitude of one Israelite to another but the ownership of a man or woman who was a non-Israelite. They could be beaten and passed on as chattel to children.Your god does not get that it is dehumanising for one human to own another human.
What convinces you that slavery is wrong? If there's no God to declare it wrong, then there's no immorality involved at all. Yet it is wrong under most circumstances. But under the Mosaic Law, it was permitted, albeit with a host of restrictions designed to preserve human dignity. Your god, Cofty, has no virtues or vices. There is, in your mind, no goodness in him, nor evil, because (as you said) he doesn't exist. Yet you claim to be arbiter enough to judge Yahweh for allowing the servitude of men one to another. Again, how do you know forced servitude is evil if there is no God? Who told you it's evil? ("Who told thee thou wast naked?") Who put it into your mind? Were you born knowing it? How do you know torturing animals is wrong? Or anything else?
By the way most of the OT law was plagiarised from the code of Hammurabi.
It is true that both appear to have a common source, but no one knows who devised the code or from whence it was derived. Since God gave the law to Moses, I suspect it was given before. Of course, if there is no God, then some ancient probably wrote it and some sneaky Hebrew scribe stole it and attributed it to the Hebrew God. But even then no one knows for sure. Stuff that old is mostly conjecture. It's just like the story of the ancient flood. Just because a version is the oldest known does not mean it's the original. The flood is a tradition had among the Babylonians, Greeks, Romans, Jews, Mayans, Olmecs, Aztecs, Asians, North American natives and many other peoples. The oldest we have extant is the Babylonian. But that doesn't mean it originated with them. So my answer to you is, please stop spouting off stuff you read on your little atheistic bull boards and start proving your points.
Oh, and one last thing. How do you know there's no Satan? 😈
