According to the Mayans’ understanding and vision of the world, 2012 is the end of one cycle and the beginning of the next cycle, which is the same as ours day after day and year after year.
Unfortunately, when the Spanish invaded South America, they massacred all the Mayans who could read and write, which led to a serious regression of Mayan culture, so much so that they hid in the rainforest and degenerated into primitive people. Many years later, European scientists began to study the Mayan culture and discovered that the Mayan calendar ended in 2012. Because of their ignorance of this mysterious culture, some people made the statement that "2012 is the end of the world." In fact, if the Mayan culture had not been extinct, a new chronology would definitely have been proposed, and there would be no such statement.
