That’s not true- the mere existence of you and the actions you’ve taken were and continue to be woven into the state of the universe since the day you were conceived. You made a direct and irreversible contribution to the increasing entropy of the universe and have helped push us all one step closer to ultimate equilibrium and the heat death of the universe. Be proud of your work, it is no more and no less than any other human or collection of atoms that has existed to date or ever will exist.
