Has the person who wrote this heard of a little thing called ancient Egypt, which had an ethical system that was likely the origin of Moses’ ideas? Or ancient Greece, and Rome, both of which had a lot of lads (and a few lasses) who gave rather a lot of thought to ethics, and matters of that nature, including philosophy? 
Or, India, the Vedas, and the Gita, the principle of ahimsa…
