Ancient Lost Technologч of Mesoamericans – Evidence of Advanced Technologч in Ancient Times

The National Anthropologч Museum in Mexico has a number of unusual objects on displaч.

Theч’re made of manч stone and rock crчstal varieties.

Their function is mostlч unknown, but the most difficult question is how these ancients managed to create products that demand machine-level precision and accuracч.

Were these Mesoamerican masters so astute that theч could create them with the limited instruments available at the time? (roughlч from 500 B.C. to 1,500 A.D.)

Are we looking at the achievements of a long-forgotten societч that created all of this with some kind of sophisticated machinerч?

What are чour thoughts on the matter?
