Modern humans, being perhaps over 1 million years old, have been star gazers for a hell of a long time. They wouldn't need an astronomy lesson, but could instead teach one! I'd bet you they all had at least one name for Orion's belt, for instance. Probably the dippers and Cassiopeia, too. And on and on, including Taurus, the Twins and Aquarius.

Ancient civilizations pretty much all developed calendars, obviously experienced seasons, often had rituals based on astrological events and seasons, had holidays, and in most cases months would be based on the lunar cycle.
