We love a vast number (or at least I do). Tell someone the observable universe is ninety three-ish billion light-years across and watch their face go soft with wonder. Tell them a single galaxy holds a few hundred billion-ish stars, and they’ll call it humbling, beautiful, the good kind of small. We’ve built an entire aesthetic out of cosmic vastness. We put it on posters.
But point that same vastness backwards—not outward into space, but back into our own time—and something in us flinches. We go quiet. Then, oddly, we go certain. We start talking about history as if we’ve actually read it.
Here’s the thing I keep turning over. Anatomically, we’ve been us for something like three hundred thousand years. Writing is maybe five thousand years old. Do the arithmetic and the conclusion is almost rude: everything we call “history”—every name we can pronounce, every quote we can attribute—fits into the last couple percent of our existence. The other ninety-eight is dark. Not metaphorically. Actually dark. Billions of people lived whole lives in it. They fell in love, buried their children, argued about the moon, said something on a riverbank that someone else carried to their grave—and not one syllable of it reaches us. A while back I wrote about the stories we carry silently. This is worse. These stories weren’t carried silently. They weren’t carried at all.
And the strange part is how comfortable we are with this. We don’t lie awake over it. A clean timeline is cozy. It’s so much easier to live inside a story with a beginning you can point to than to admit the beginning is simply unlit.
It gets thinner. Even the lucky two percent that did get written down mostly didn’t survive. We treat the past like a library we can walk into. It isn’t a library—it’s the ashes of one. Of the great Athenian tragedians, well over a thousand plays were written, and somewhere around thirty survive. Sophocles alone wrote roughly a hundred and twenty; we have seven. Lucretius’s poem on the nature of things—one of the most important texts of the ancient world—came down to us on a thread so thin it’s almost funny: rediscovered in a monastery in 1417, after centuries when barely anyone had a copy. A bit more damp, one more careless fire, and we’d have nothing—and here’s what unsettles me most—we’d never have known there was a “nothing” to miss. We don’t read the past. We read whatever happened to dodge mold, war, and human indifference, and then we mistake the survivors for the whole.
Survivorship bias, but for a species.
Sometimes we even have the people and still can’t hear them. The Indus Valley civilization was enormous—planned cities, standardized weights, drainage that would embarrass parts of the modern world—and we can’t read a word they wrote. Their script sits there, fully preserved and completely silent. We don’t know what language they spoke. We don’t know what they called themselves. We named them after a river.
Now hold all of that, and bring in the floods.
When the last ice age ended, the seas rose by something like a hundred and twenty meters. Whole inhabited plains went under. Doggerland—where you could once walk from Britain to Europe across hunting grounds now buried beneath the North Sea—is just the famous one. And here’s the quiet, obvious problem nobody wants to sit with: people live on coasts. Always have. So the single most likely place to find what we lost is exactly the place we almost never look—underwater, under silt, under the new shoreline.
This is usually where someone says “advanced civilizations” and everyone rolls their eyes, and I get the reflex. But I want to be careful, because the reflex is doing something dishonest. We don’t reject those ideas because we know they’re false. We reject them because we’re confident—and confidence about the deep past is a costume.
Consider that we have a documented case. Around 1177 BCE, a genuinely sophisticated, interconnected world—Egyptians, Hittites, Mycenaeans, trade routes humming between them—collapsed in the span of a few decades. Cities burned. And literacy itself went with it: the Greeks forgot how to write for roughly four hundred years. Sit with that. A system robust enough to feel permanent to everyone inside it fell so completely that the very ability to record fell too. That isn’t fringe speculation. That’s the textbook.
So when I’m told, flatly, that nothing could have risen and fallen so hard that we’d struggle to find its ruins—I don’t believe the opposite. I just don’t think we’ve earned the certainty with which we call it impossible. The category is real. We’ve watched it happen. The only open questions are how far back, and how completely.
I’m not here to sell you a lost golden age. I just wanted to say it out loud, the way you say a heavy thing to see how heavy it is. We’ll keep staring up at the galaxies and calling the bigness beautiful. I only wish we’d aim the same humility backwards—at the dark we crawled out of, full of people exactly as real as us, wondering exactly the things we wonder, whose names we will simply never know.
History isn’t a record. It’s a rumor that happened to survive.
