Maya people belong to Guatemala

Explanation:

Guatemala is the domain to volcanoes, tropical forests, and traditional Mayans, a Central American nation south of Mexico.

In southern Mexico, Guatemala and northern Belize, the Mayan Mesoamerican Indians live on almost continuous territories. More than five million people, many of whom were multicultural, spoke Mayan in Spanish in the early 21st century.

The written story of the Mayan mentions that chocolate beverages are used in religious festivals and in order to complete important trades.  

In Ancient Egypt around 3 B.C the first documented zero was recorded. The Mayans spontaneously invented it about 4 A.D. This was subsequently built in India in the mid-fifth century and expanded to Cambodia at the end of the seventh century.
