If you wanted to design a writing medium that enables archeology, it would be difficult to do better than clay tablets. Fired clay is great for records meant to last, being very fire and water resistant, while unfired clay was reusable if you just made it a bit wet again, great as reusable writing surfaces. So many paper, parchment and papyrus records that were meant to be kept have been lost to fire and water over the millennia. Yet with clay tablets a fire not only struggles to harm the records that were meant to last, it turns all the temporary records, scratch pads and notes left around into long-lasting fired clay. Burn a Sumerian city to the ground and you create a snapshot of all their writing for archeologists to find millennia later
