A Finnish linguist, Kalevi Wiik, a couple decades ago, proposed that northern Europe originally spoke "Uralic" (of which Finno-Ugric is the largest division). If the original boat peoples arose from European reindeer peoples, and if after the development of the use of boats, they expanded in every direction from their north European origins, then indeed, before the development of farming-based Europe, before the arrival of Indo-Europeans, northern Europe could very well have spoken Finno-Ugric as Wiik suggested, including all regions later recieving the Indo-Europeans that gave rise to Celts, Germanics, Slavs and Balts. Wiik tried, in his papers in the 2000's to imagine how the Finno-Ugric boat-using hunter-gatherers responded to the immigrant peoples, from the farmers to the cattle herders in those millenia between 10,000 years ago and about 5,000 or 4,000 years ago. That is about 5,000 years of the original hunter gatherer peoples with boats, north of the Alps, interracting with and adapting to the presence of newcomers.
