Space, because writing could be sent from one place to another. Time, because writing could preserve the words for generations to comePSince the art of writing was discovered, nearly every form of writing material has been used. Some were intended to ensure permanence 永久while others were simple and inexpensive but temporary暂时的.

This tablet was then fired to harden it and make the message permanent.
