Many millennia before any person would look through a telescope or ride a rocket ship into outer space, our ancestors gazed up at the night sky with fascination, reverence, and a deep desire to know more. Early stargazers tracked the movements of stars and planets and found ways to incorporate them both practically and symbolically into their daily lives. People used this intricate knowledge of celestial objects and events to tell time and navigate, but they also used the stars and planets to tell stories, build societies, and most remarkably understand their own human relationship to the universe surrounding them.
