There was no point or rationale behind existence in creation. Once it was not and now it is. Perhaps eventually it will not be again. Before that, in the between which we exist and live, there is no driving purpose. Seemingly depressing, I find it helpful. If there is no overarching grand reason, only the micro reasons count. The reason you get up in the morning, the reason you chose to come to college, the reason for continuing to live and push every day, those are the only ones that matter.
