the oldest proof
  1. at least 67,800 years ago, on a small island in indonesia, someone pressed a hand against a cave wall and blew red pigment around it.
  2. it is the oldest art ever found. no name. no words. one message: a human was here.
  3. 2026. the feed is ai. the replies are ai. the art is ai. half the coins on your screen came out of a prompt.
  4. now people have to prove they're real. a man got accused of using ai for an ad he drew by hand.
  5. so we went back to the first proof.
  6. one hand. one wall. HUMAN.

2. blowblow paint around it. a straw and some watercolor works. so does a spray can.
