Perhaps one of the most curious artifacts of antiquity is a stone disc weighing 2 kg, which archaeologists have found in Colombia. On its surface are carved images that amaze modern people.
The fact is that it depicts things and processes that we can observe only under a microscope: on a disk, the process of the birth and development of an embryo is shown. Also, one of the strange drawings is the head of a person of an incomprehensible shape.
The disc is made of a durable stone called lidite. With its exceptional strength, this stone has a layered structure, and, despite the presence of this ancient artifact, it is not possible to make something similar to it both practically and theoretically.
Sexual distinction between men and women.
The diameter of the disc is 27 centimeters. The entire process of the birth of a human being is depicted with pinpoint accuracy along the circumference of the disc - on both sides - from the device of the productive organs of a man and a woman, the moment of conception, intrauterine development of the fetus through all its stages - until the birth of a baby. Scientists have seen many of these processes with their own eyes relatively recently, with the help of appropriate instruments. But the author of the disc possessed this knowledge perfectly and was, apparently, a sixth-grade geneticist, because next to human beings you can see not quite human ones.
There is a circular hole in the center of the disc, so most likely it was pushed onto some kind of rod and rotated.
