Traditionally, two areas of origin are attributed to the Germans: southern Scandinavia and Jutland. However, these theories have significant drawbacks. In southern Scandinavia, there is a lack of continuity in archaeological cultures, meaning that the Germans did not develop there but arrived already formed. Moreover, Denmark and Germany were controlled by dominant Celts, and it is unlikely that intolerant Celts would allow for the extensive and prolonged formation of a new superethnicity of Germanic peoples. Additionally, in the general epic and beliefs of the Germans, the sea is not dominant, as it is specifically for the Scandinavians and Frisians, but rather the forest and swamp prevail.
Therefore, the homeland of the Germanic peoples may be the Chernobyl region (Southern Belarus, Northwestern Ukraine), supported by numerous toponyms of corresponding Germanic tribes: Teutons, Franks, Goths, Anglo-Saxons.

The Sarmatians, who succeeded the Scythians, displaced the Germans from the Chernobyl region to Jutland. In their place, a fusion of Sarmatians and remnants of the Germans gave rise to the early Slavs - the Veneti.
Whether the Chernobyl disaster was accidental or a deliberate radiation scorching of the cradle of two civilizations, the Germans and the Slavs, to prevent the formation of a new superethnicity in the future?
