And as change is constant in this world, many systems also come to an end. There are ones that are made on a timetable like plays and presentations., with an end date that the 'creater' is able to witness. How do they feel, what do they think about when that happens?
Also it makes one realize that we too are creatures in this vast system that we are all a part of, that we share with other people, animals and other matter. Are we bringing our Creator joy?
