maybe there exists a universal moral code that is part of the fabric of existence that our species alone has the mental tools to contemplate. These conclusions are natural outcroppings of our why specialist nature. Combine this line of inquiry with our death wisdom and you have the question of “why do you have to die?,” which is intimately tied to the problem of how we should behave while we’re alive in case it impacts what happens to us in the afterlife.
Being able to question why + knowing everyone will die leads to trying to understand WHY DEATH happens. This leads to the evolution of eschatology.
