The conversation was about the basis of American law and human law. People claimed American law was directly based on the Ten Commandments. It wasn't, it was based on the entirety of human law history. The Torah was itself a small piece of a much larger legal tradition in the ancient near east. Americans only have this delusion about the Commandments because biblical history is widely taught while no one mentions Sumerian, Babylonian, Assyrian, Scythian, or Persian history. They were all happening simultaneously and had all arisen from literally millennia of human society in the area. The Bronze Age and even earlier in that part of the globe was a highly interconnected web of cultural, economic, and political exchange.
This is exactly what I've been saying all day. The legal basics were already universal at its time of creation. It has remained notable and exceptional in history for these other reasons you highlight.
