We are in many ways unimaginably small within this universe, yet uniquely special. We have the power to go to space, are self aware, and masters of our own destiny. Yet we are on a small planet circling a very average star, spiraling around a massive galaxy of hundreds of billions of stars. That galaxy, on top of that, is just one of billions of galaxies. Yet we are alive today, and that is a gift no one can undervalue.
