The Spread of Archeological Cultures associated with Finno-Ugric languages.

The video I linked seems to give some interesting perspective on the Finno-Ugric peoples as they spread through Eurasia. The fact that they excelled in Bronze-work makes more sense to those on this Forum who will have heard how the Frya's had Iron even in the so called bronze age, wheras Finda's folk had only flint and copper(The main ingredient in "Bronze" for Indo-Iranic people).
Most of the dates match, though the invasion of East Skeanland would be dated later in this model.

The linguistic and cultural divide between the Sami, Finns, and Estonians in the west and their Siberian counterparts in the east aligns with the OLB narrative that posits the displacement of the Finns by another people, the Magyars, who are believed to have arrived from the Altai Mountains, a region also known as the origin of the Moghuls/Mongols and the shamanic priest people who exerted significant influence over the Indians. Consequently, the linguistic gap in Eastern Europe can be attributed to the early migration of the Magyars.

The Slavic languages, therefore, are likely the result of the amalgamation of the Finns, Magyars, and Fryas, specifically the Swedish settlers from Roslagen. Prior to this development, the concept of a distinct Slavic people, as they are recognized today, was nonexistent. It is plausible that Gosa's letter concerning the purity of language was intended as a commentary on the early Slavs, a period during which they were still consolidating their identity as Rus and spoke an inconsistent form of Proto-Slavic.

The term "Aldland" is a generic designation for "ancestral lands." Consequently, when the OLB Findas migrated from Aldland and the Fryas migrated from the submerged Aldland, it can be interpreted that they each sought refuge from the devastated regions of their respective homelands in response to the 4.2 ka event.In this context, the Finda homeland is theorized to be situated in the Altai Mountains (or more broadly within Central Asia). The Frya homeland, on the other hand, is believed to be Europe, and perhaps the island of Frisland, as depicted in ancient maps, a topic discussed by Alewyn J. Raubenheimer in Chronicles From Pre-Celtic Europe. When the Fryas asserted that the Finda Aldland lies beneath the sea, it is plausible to infer that they presumed the Findas also experienced seismic events and floods similar to those that afflicted Europe. However, due to the vast distance separating them, there was no means to verify this supposition.

I still haven't read Chronicles From Pre-Celtic Europe., but now that I've been saving I should go ahead. I'm still not sold on this "Atland being the homeland of Fryas", but i might as well hear the late writer and what he has to say.
