Why We Carve: 75,000 Years of Marking What Matters

Why do we carve our names into things? This episode traces a single continuous human behavior from the earliest known engravings in Blombos Cave to a rotary tool in a Jerusalem kitchen. We explore the engineering behind permanent marking — why a thirty-dollar engraver plus a paint marker outperforms adhesive labels and laser systems — and the psychological driver that makes us insist on permanence in an impermanent world. For anyone who has ever felt the urge to scratch their presence into something solid, this is the story of why we do it and how to make it last.
