The Sumerians lived some 5,000 years ago. They had no telescopes that we know of. Yet they clearly knew of 12 ‘celestial bodies’, including the sun and the moon. They depicted the 12 planets and wrote about them on stone tablets. The Sumerians described not only the existence of these celestial bodies, but knew exactly their names and roles in the solar system and the universe. Were they masters of mathematics and astronomy? Or did they stumble on a great and ancient secret only the chosen in Egypt and Mesopotamia were told?
