How Did Ancient Civilizations Communicate Over Long Distances?

Long ago, people used special ways to talk to each other even if they were far apart. Imagine you're on a mountain and you want to tell your friend in the valley what's happening, you could light a fire or send smoke up into the sky! That’s how ancient people like the Native Americans used smoke signals. They also used messengers, like runners who would carry messages from one place to another, kind of like a super-fast postman.
