Have you ever heard of the Reformation? Gosh, do you think that the notions of DIVINE law (expressed as "nature's law" in the Declaration of Independence) by the founders, had an influence on the piligrims, puritans, and the Christian founding fathers? Do you supppose that God-given inalienable rights came from the Romans? The 10 commandments are the foundation of American Law and the founders said so. These commandments are emblazoned on the Supreme court building. Why is that? Why is their a mural in Congress depicting Moses? Why is a bible verse from Leviticus inscribed on the liberty bell? It seems you are the one that has some 'splainin to do.
I'm not your history teacher. Why don't you go look up Grotius, Puffendorf and Locke and read what they wrote (also Vattel). Why don't you check and see who influenced our founding fathers the most? It wasn't the Romans!
