- Historic Period: Around 4,000 BCE – Babylon, Greece, China, Egypt
Astronomy is the study of movements and patterns of celestial bodies. This includes things like the sun, moon, and stars. Early on, astronomy was seen as an important science that could indicate what might happen in the future. This is why many ancient civilizations kept incredibly detailed star maps and astrological records overall. The assumption was that you could tell anything from how the stars looked, but most of this was complete BS. This led to an eventual separation between astronomy (actual science) and astrology (pseudoscience). As far back as 4,000 BCE cultures in Ancient Greece, Babylon, China, and several others used astronomy constantly. In fact, many Kings and Queens relied on this information so much that they were given daily records of star, moon, and sun positioning.
