I asked ChatGPT at AI:

Do all homo sapiens societies have Ethical codes:

As of my last update in September 2021, it can be generally stated that all human societies have some form of ethical codes or moral principles that guide their behavior and interactions. These ethical codes may vary significantly from one culture or society to another, but the concept of morality and ethical guidelines is nearly universal across human civilizations.
Ethical codes are often shaped by various factors, including religion, philosophy, cultural traditions, historical experiences, and practical considerations. These codes provide a framework for determining what is considered right or wrong, just or unjust, and they help maintain order and cohesion within a community or society.
It’s essential to recognize that while many ethical principles might be common across societies (e.g., prohibitions against murder, stealing, etc.), the specific values and moral guidelines can differ significantly due to cultural diversity. Ethical codes can evolve over time, reflecting changes in societal norms, and they are often subject to debates and reinterpretations.
Keep in mind that my knowledge is up to September 2021, and developments beyond that date are unknown to me. Thus, it is possible that changes or shifts in human societies may have occurred after that time.

So, all Homo sapiens societies have moral codes.

How much time do you think people spend thinking about the moral codes they use?
Ethical behaviour is based on the intrinsic value of each individual.
Homo sapiens as other species has to survive and while doing so, has to enjoy the days of life, because it is short.
We try to make sense of life and try to make it better.
Looking at life Homerically, we see a battle, the Iliad and a journey, the Odyssey.
The question is:

Where does Odysseus start to act as an individual?

Each of us who experience our self, know that it is embedded in a continuum of the empirical substratum of developing life in our Universe.

So, the task for Homo sapiens is to generate an ethical footing.
For if Homo sapiens have ethics on their minds in all cultures, then ethics must exist in the reality of the Universe we grow out of.
Pointing to that, is the role that our living brings to each of us.
