Who are the Mayans and why are they what they say?

The Mayans were able to burn exquisite pottery more than 4000 years ago, and the level of stone carving was already very high more than 2000 years ago. The Mayans were mainly distributed in southern Mexico, Guatemala and northern Honduras, and established the Maya dynasty that was the most proud of the world. In 800 AD, the poor rioted in Cancun, Guatemala, and brutally exterminated the royal family. This incident quickly caused a chain reaction in all tribes and more than 50 cities. The Mayan dynasty collapsed. The killers fled in all directions. Pyramids, palaces and shrines turned the city into ruins. After the Sui Dynasty, Mayan culture was submerged in the rainforest. If the Mayans can predict anything, why can't they predict themselves? It is wrong for later generations to blame the Spanish for the restoration of Maya.

However, the history of Maya's death warns people today.

Mayan monuments leave us with several mysteries: 1. Before 2000, when there were no means of transportation and no roads, how could we move several tons of stones to build thousands of pyramids on wetlands? .......
