Simmerian had the some understanding about our solar system , according to the printed cylinders. https://www.google.com/search?q=sumerian solar system&sa=X&espv=2&biw=1680&bih=817&tbm=isch&imgil=5S77fvI383oeHM%3A%3BEG7DXd0qIGUvfM%3Bhttp%253A%252F%252Fbogdanfiedur.blogspot.com%252F2013%252F10%252Fthe-12th-planet-sumerians-and-their.html&source=iu&pf=m&fir=5S77fvI383oeHM%3A%2CEG7DXd0qIGUvfM%2C_&usg=__3PygcaLrmjHXB7XU5oIPzrJdt6E=&ved=0ahUKEwjQn4Gqj6zJAhUGFj4KHdCaDFQQyjcIJQ&ei=nfJVVpDdEIas-AHQtbKgBQ#imgrc=O5JvBhHfClZOHM:&usg=__3PygcaLrmjHXB7XU5oIPzrJdt6E= https://www.google.com/search?q=sum...0ahUKEwjQn4Gqj6zJAhUGFj4KHdCaDFQQsAQIGw&dpr=1
Astronomy can fairly be called the First Science. There's plenty of evidence that people had learned to use the position of the sun, moon and stars to accurately predict the seasons in the Paleolithic Era. Possibly by the dawn of the Neolithic Era, but certainly the Bronze Age, they had noticed the two-millennium cycle of the constellations that make up the Zodiac. The Sumerian (check your spelling) civilization, which was established by 4000BCE at the latest, was well advanced in astronomy and astrology. Mercury, Venus, Mars, Jupiter and Saturn are visible to the naked eye (telescopes were not invented until several thousand years later) and they were able to predict their orbits with remarkable accuracy.
Sorry, I got it wrong. It's more like a 25,000 year cycle. To start now, the Sun appears to be in the constellation Aquarius--this is why astrologers proclaim the next 2,000 years to be the "Age of Aquarius." I'm not very well versed in astrology, but apparently Aquarius, the "Water Bearer," has some traits which they find to be eerily matched to the issues that have begun to dominate the era, such as the importance of science and the spread of love and peace. (Obviously this was an easier sell in the 1960s when "Hair" came out with its iconic song "The Age of Aquarius." Nowadays, humanity has sunk back into war and hatred.) The previous Age was the Age of Pisces, when the sun appeared to be in that constellation. Pisces is the Latin word for "fish" and by golly, the dominant motif in Western civilization was Christianity, with its fish symbol. Two millennia before that was the beginning of the Age of Ares, which is a symbol of war. And indeed, the last two millennia before the Year Zero on our Christian calendar were marked by nearly constant warfare. The galaxy does not actually revolve "around us" in a precise 24,000-year cycle--it's more like 25,000. So the astrologers 25,000 years from now (assuming that there are still astrologers, or even humans Please Register or Log in to view the hidden image!) of that era will have to make up some looney tale to explain the discrepancy. I'm sure they'll have no trouble!
