The ancient Mesopotamians - the Sumerians - were the first to keep astronomical records. Let's discuss what they recorded and when. Did their ziggurats double as their observation towers? Were they the first to record the 4 seasons? Was their first Zodiac 4 constellations? What was their connections of astrology and astronomy all about? What remnants of Babylonian astronomy is in use today? We need strong evidence with resources/links. (I'll be contributing to this as I collect the data with sources.)
