One does not need to believe in the supernatural or an imaginary Sky-King to have a moral and ethical code. Humans have developed a moral code over many thousands of years existence. They are good, not because some mythical God orders them to be good but because it of a natural, evolutionary process which works to the betterment of us all..
I’ve lifted these “new” commandments from Richard Dawkin’s book,The God Delusion but they did not originate with him. I’ve also added a few more of value. I strive to live by them. You may have additions of your own.
1. Do not do to others what you would not want them to do to you
2. In all things, strive to cause no harm
3. Treat your fellow human beings, your fellow living things, and the world in general with love, honesty, faithfulness and respect.
4. Do not overlook evil or shrink from administering justice, but always be ready to forgive wrongdoing freely admitted and honestly regretted.
5. Live life with a sense of joy and wonder
6. Always seek to be learning something new
7. Test all things; always check your ideas against the facts, and be ready to discard even a cherished belief if it does not conform to them.
8. Never seek to censor or cut yourself off from dissent; always respect the right of others to disagree with you.
9. Form independent opinions on the basis of your own reason and experience; do not allow yourself to be led blindly by others.
10. Question everything
11. Preserve things of beauty for future generations to enjoy
12. Tell the truth
13. Resolve conflicts with dialogue rather than violence
14. Oppose injustice
15. Take full responsibility for all your actions
16. Do not indoctrinate your children. Teach them how to think for themselves, how to evaluate evidence, and how to disagree with you
17. Enjoy your sex life(as long as it damages no one else) and let other consenting adults enjoy theirs in private, whatever their inclinations. which are none of your business
I’m sure you can think of others. Suggest them and I might include them in my list
