Final answer:
The Maya did not create a centralized state; their civilization was a loose network of city-states. They were known for advanced astronomy, a unique calendar system, and a sophisticated writing script. They also had developed agriculture and trade networks.
Step-by-step explanation:
The Maya civilization accomplished many things, but one statement that is not true is that the Maya created a centralized state. Instead, their civilization consisted of a network of city-states that were involved in intricate relationships of trade, alliances, warfare, and cultural exchange. These city-states, such as Palenque, Calakmul, Caracol, Mayapan, and Tikal, were independent entities often competing with each other, rather than unified under a single central government.
When discussing the Maya, it is crucial to highlight their advanced knowledge in astronomy and mathematics which they incorporated into their unique calendrical system, allowing them to predict astronomical events like solar eclipses precisely. Aside from their scientific achievements, they were also known for their written script, which was a combination of pictographs and alphabetic elements, enabling them to record history, astronomy, and religious texts.
The civilization's trade networks and agricultural practices were also sophisticated, with a variety of goods and crops being traded and cultivated across their territory. This included the importation of luxury items such as gold and turquoise, as well as the cultivation of staple crops like corn, beans, squash, and chili peppers.
