Look! You are only describing LINEAR TIME, what about NON-linear time? Ie: the perception of time experienced as a whole in every part of the time/space continuum..... We simply fail to understand that time has no begining and no end. And trying to understand that is a recipe for insanity. Time did not begin with the Big Bang! It merely continued. As for the 'meaning of life': to experience time is to create one's own reality and our 'reality' is only our limited way of dealing with a universe that is simply too big for us to contemplate.
