Earth photographed by the Voyager spacecraft from 3 billion miles away. Still within our solar system.
One small planet in a solar system. Trillions of solar systems in our galaxy. Trillions of galaxies in our universe. Earth like a grain of sand on a very, very big beach, with seven billion atom sized entities clinging to it, all proclaiming their importance and their opinions and their understanding of the nature of things.
If we’re not alone, we’re pretty insignificant. If we are alone, we’re still pretty insignificant. Even collectively as a species, a phenomenon. Never mind as individuals.
I don’t know whether we have meaning, or what that meaning might be, but I suspect that either what we perceive, vis à vis this photograph, is illusory and we actually stand a chance of meaning a great deal in some unappreciable way in a different kind of universe that we can’t imagine, or it’s not illusory, in which case we’d better get our heads out of our arses and grow up a bit, because no one is going to give a shit if we decide to cease.
