Opinions on Morality?

When you read the first 5 books of the Bible..those scriptures were written by Moses. The laws that were established for the Nation of Israel were benchmark laws and did not exist before that time. Most of the world were amerced in pagan practices, barbaric behaviors and almost animalistic in nature. Read up on Aztecs, Mayans and ancient cultures of Rome and Greece. Pretty bad. You can thank the Jewish Nation for being the first to adhere to any type of morality as established by God in an immoral world.
