From this distant vantage point the Earth might not seem of any particular interest. But for us, it’s different. Consider again that dot. That’s here. That’s home. That’s us. On it, everyone you love everyone you know everyone you ever heard of every human being who ever was lived out their lives. The aggregate of our joy and suffering thousands of confident religions, ideologies and economic doctrines every hunter and forager every hero and coward, every creator and destroyer of civilisation every king and peasant every young couple in love every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every superstar every ‘supreme’ leader every saint and sinner in the history of our species lived there. On a mote of dust, suspended in a sun beam. The Earth is a very small stage in a vast, cosmic arena. Our posturings our imagined self-importance the delusion that we have some privileged position in the universe are challenged by this point of pale light. Our planet is a lonely speck in the great, enveloping cosmic dark. The Earth is the only world known so far to harbour life. There is nowhere else, at least in the near future to which our species can migrate. Visit? Yes. Settle? Not yet. Like it or not, for the moment, the Earth is where we make our stand. It has been said that astronomy is a humbling and character building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another and to preserve and cherish the pale blue dot. The only home we’ve ever known – Carl Sagan.
