Germanic lineage arrived from the east?

[Rodoorn]

Rodoorn:

It seems that the Germanic lineage was present within the Scandinavian Bronze Culture ("Nordic" seems to me too tied to the modern Nordic languages). But we cannot claim that it was the only language within that cultural sphere, or that there were no Para-Germanic languages in there or in some other regions.

Why can't we claim that? What withholds us that with a kind of NBA cultural expansion the language wasn't expanded also? Is it total coincidence that the Elbe-Havel group usually seen as the ancestry of the Suebi, with the Semnones tribe at it's core (at least when we have to believe Tacitus in this respect). Why we must have such a restrain? What is the need and necessity of such a restrain.

Well, naturally you can claim whatever you want to claim. But claims are futile when there is no way to verify or falsify them - then it is better to remain agnostic. Language still cannot be seen from cultural or genetic similarity or continuity, and it never will be. We should only make claims about things for which we have supporting or dismissive linguistic evidence.

Well as you claim this:

"It seems that the Germanic lineage was present within the Scandinavian Bronze Culture."

Then it's not fare fetched that claiming that people that were part of the Scandic Bronze Culture like the Havel Elbe Group and the Suebi derived from this group most probably belonged to the Germanic lineage. That's no wild guess.

True, it is not a wild guess.
