Because they had ''eyes'' and the sky was dark... seriously?

The important breakthrough was when ancient civilizations invented writing, so that they could keep records of events in the sky. It's amazing how much you can learn through careful naked-eye observation, especially if you built large instruments. Read up on Tycho Brahe and his observatory at Uraniborg, Denmark.

As far as the planets go, they knew of all of them from Mercury out to (and including) Saturn, because they are all visible to the naked eye and they had observed that their position among the stars changed - that's why they were called planets, which is closely related to Ancient Greek for "Wandering Stars". As far as maps were concerned, what they had were pretty crude by present day standards, not just because they didn't have aircraft or satellites, but because they didn't have the Maths or instruments necessary to survey coasts. In fact a lot of their sailing was done along "line of sight" and with their fingers crossed.

Whilee lacking telescope and spacecraft they had devices such as astrolabes and quarterstaffs for measuring locations and motion. Plus major construction projects such as Stonehenge in England and some similar stuff in North America (medicine wheels) and Korea tracked seasons, lunar phases and eclipses.
