(From a secular point) Who is or was the author of your morality?

(Disclaimer: This is not for followers of God, Christ, Christians, or believers of any religion. This is a question in the spirit of humans and humans only, no deities, supreme beings, spirits, extraterrestrials, mythical beings, or entity from other than the earthly realm)

Who created of formed the reality you live by, no matter how deep generational you have to go? Whether it came through parents, great grandparents, great great grandparents, or back through 1,000 year genealogy of your family etc; however it filtered down to you, who was the one who created it? Did you derive at it by trial and error, you were told not to steal so you stole something to see if the negative reality or action would happen? Same thing goes with being stingy, lying, cheating, and assaulting people? To know if it was correct you tried it to see what would happen? If you never purposely did any of those things to test if it was good for you or not, why didn’t you? Did you not do those things consciously because you were told not to by someone, parents, grandparents, family school, etc? If you believed them, where do you think they originally got their morality from, which person, group, government, etc, and how far back in history did it come from; years, decades, etc?
