It might be because the answers to those questions could be different for everyone. Think about it. Not to mention this is a programmed device most people probably dont know the answer to be able to program it in. A lot of people may not even thinkbabout that question. The nature of it seems to come from a state of depression to me. To try and answer that question for you though i would say that the point to do anything is simply because we are alive. We are consciousness. And we are alive and we have the need to express ourselves so that we can feel that we are alive. In otger words if we did nothing just because we are going to die then what is tge point in being alive anyway. Enjoy life.
