A sound that travels at 340 meters per second in the air becomes inaudible after a distance. However, an inscription on a suitable ground can remain in place for centuries. Throughout the history of humanity, those who wanted to convey a word or an object to a long distance placed them in written papers and packages called letters and entrusted their messages to someone assigned for this job. So they invented the postal system. The history of postal systems, which exist to transmit messages from one place to another, begins with the invention of writing and may even be one of the reasons for the invention of writing. In this video, I told the development of postal services in ancient civilizations.
