The universe is huge. Time is impossibly vast. Trillions of creatures crawl and swim and fly through our planet. Billions of people live, billions came before us, and billions will come after. We cannot count, cannot even properly imagine, the number of perspectives and variety of experiences offered by existence.
We sip all of this richness through the very narrowest of straws: one lifetime, one consciousness, one perspective, one set of experiences. Of all the universe has, has had, and will have to offer, we can know only the tiniest fraction. We are alone and minuscule and our lives are over in a blink.
