The Sumerians were rather advanced—they became the first in the Near East to use a wheel, to create an irrigation system and their unique writing. And besides, they were impressively good at maths and astronomy.
	Maya     Some scientists believe that they are connected to legendary atlantes (男像柱), others suppose their ancestors were Egyptians. It's thought that the Maya created an efficient agricultural system and had deep astronomy knowledge. Their calendar was used by other people of Central America. Maya applied the hieroglyphic writing (象形文字) system. Now it seems that the Maya came from nowhere and disappeared nowhere.
