All That Vastness Out There

I am so small so very small whilst all that is out there is so big so vast how then can I be of any value hold any worth other than to consider that my time down here is temporary a stepping-stone to something so much bigger surely even as small as I am this brief time down here between birth and death cannot be all that there is with all that vastness out there there must be more or is there what if this brief time down here between birth and death is everything and all that vastness out there is none of my concern what if all my focus, all my ability, all my energy should be concentrated not on all that vastness out there and what it may hold and what it may mean but on me down here and all that that encompasses what if just being me down here is all that there is and all that vastness out there when referenced to me is just that and nothing more.
