Yes. There remain people who doubt this, but they are not the only formation of that kind. There's a chapter or so about this in the book I linked.
You’re not fooling me again!
Last time I read a book you suggested, I got it stuck in my head that the original lands of Homer (Iliad and such) was the Nordic lands of the Baltic, and all Indo-European peoples were originally from the arctic area pre-ice age.
I don’t know what kind of crazy you’re trying to stick in my head this time, but I ain’t falling for it, buster!
... So, what else is that book about? Sounds interesting.
