Boneglyph

By: Sterling, David C.

Ninety-nine percent of everything that has ever walked, built, or thought on this planet has been erased by geological time. Not lost - erased. Continents fold into each other. Mountains grind to sand. Whole coastlines vanish beneath the sea and resurface, scrubbed clean, a hundred million years later.

So here is the uncomfortable question this book asks: if an intelligent civilization existed on Earth before us - say, a hundred million years before us - would we ever be able to tell?

Boneglyph takes that question seriously. Drawing on geology, paleontology, and the same reasoning astrobiologists use to search for life on other planets, it builds a careful, evidence-based case for just how little of any civilization actually survives deep time - and how easily we could be looking straight at the evidence without recognizing it.

Inside, you will find:

The real scientific origins of the Silurian Hypothesis, the peer-reviewed idea that started this entire investigationWhy the fossil record captures a vanishingly small fraction of everything that has ever lived, and what that means for finding evidence of intelligenceHow the search for alien civilizations and the search for a civilization buried in our own planet's past turn out to be the same problemWhat our own species will leave behind 300 million years from now, and whether it would be enough for anyone to notice

This is not a book about ancient astronauts or lost cities. It is a book about the limits of what evidence can survive, and what that means for how confidently we can say we are the first and only intelligence this planet has ever produced.

If you have ever looked at a canyon wall, a fossil, or a night sky and felt the scale of time close in on you, this book was written for you.
