The babylonians used writing to help them record which help them do calculations to create their calendar which is much like ours. The maya developed the mayan long count calendar they created it by using their base 20 unlike our base 10 they used this by predicting the movements of the planets and stars. Ptolemy invented the ptolemaic system it said that the earth was the center of the universe this and most other of his knowledge came from hepatitis a greek mathematician.
I understand most of this came because of beliefs which I think is the wrong way for this to happen. I know ptolemy thought that the was the middle of everything because the earth moves on axis.
Who invented astrology?
