You’ve gotten the order wrong, if you’ll forgive the pun. Law and order existed before the Bible, not the other way around.

Are you saying before the scriptures consisting of the bible were written? Because when you say things like "before the bible" you must explain under what circumstance you base that argument over. Is it based on the events of the bible, which predate everything in the secular world or do you mean before the scriptures were written? Do you believe the entire bible to be a fairy tale or some parts true and not others? If so, why and why are some parts true and not others? Bibles aren't that old, but the text within them go back long before anyone ever had a bible. Every author in the bible never owned a bible because they were the very ones who wrote the scriptures consisting of the bibles today. Law and order, as all things, have a root of origin. To make a conclusive argument on where the very concept of law and order began you'd literally have to identify the first person the very thought of it began. Or, if you believe the bible to be true, you can tell where everything began and know that law and order is rooted within the scriptures of the bible and was not some made up idea by some unknown person or people that just so happened to exist while the events of the bible were taking place. The bible literally is a history book of earth and humanity from beginning to end. There is nothing that predates it.
