How were the first letters and messages sent?

The first letters and messages were sent using simple forms of communication, such as oral messages or symbols drawn on surfaces. Ancient civilizations, like the Egyptians and Mesopotamians, developed writing systems using pictographs and cuneiform on materials like papyrus and clay tablets. As societies advanced, they began using messengers to deliver written messages across distances, often utilizing trained runners or animals like horses. This laid the groundwork for more sophisticated postal systems in later cultures.
