Fisherman - At last we get to the actual meaning of your thread.
You think that unless right and wrong is based on the dictates of your deity, and unless our actions lead to eternal rewards or punishments there is no point in being moral.
It always amazes me when believers attempt to make this point. Is it only your superstitious beliefs that keep you from murder, rape and theft?
All of us avoid harm and desire things that contribute to our welfare and pleasure. These are not simply social constructs they are objective realities. Living in a certain way contributes to the quality of our lives and those of others.
All day every day we do things that are of only temporary value. We clean our homes, tend our gardens, paint the fence and wash the car even though all of these efforts are quickly undone. They make our lives better. Being concerned about the wellbeing of others - who likewise respect our interests - also contributes to the quality of our lives. To do otherwise would lead to dystopia.
The instincts that underpin our moral decisions are a result of evolution. Far from being a "gimmick" they have made it possible for us to prosper as a social species. Despite all our failings our achievements are astonishing.
Fisherman - According to your worldview what exactly is morality?
