The Proto-Indo-European myth of the creation of the world, reconstructed by Bruce Lincoln, tells of two brothers - *Manu (Man) and *Yemo (Twin). Traveling with the bull, they decided to create the world. Manu sacrificed Yemo and the bull, using their bodies to create various parts of the Cosmos. The figure of *Yemo then became known among the Germans as Ymir, and the bull as the cow Audumla. Among the Indo-Aryans, *Yemo began to be called Yama and Purusha. The Slavs also know about the deity, whose body parts have become different parts of the Cosmos.

From Proto-Indo-European times, the Kernosovskiy idol has come down to us. This idol belongs to the Yamnaya culture of the Eneolithic era (III millennium BC), which was located in the Black Sea region and was Proto-Indo-European. Thus, it was associated with the ancestors of the Germans, Celts, Italians, Slavs, Balts, Indo-Aryans, Greeks, etc.

It is obvious that the Kernosovsky idol depicts Yemo, as indicated by a number of details, including the image of the spine in the form of the World Tree. The original idol was used in the cult of the Ancestors, placed on mounds.
