Unfortunately things got a little heated earlier in the day. It's regrettable. I must admit, however, the bolded portion jumped out at me as it did at cormac. Is it possible your comment was misconstrued? The oldest civilization by the criteria of historical studies is still Sumer, in southern Iraq. The Sumerians rose in the Uruk period in the fourth millennium BCE. It must be admitted that the exact ethnicity of the Sumerians is still obscure, and the fact that their tongue was a language isolate only adds to the mystery. However, there is nothing linguistically or culturally to connect them with prehistoric peoples of southern Russia, of which I'm aware. There is a working linguistic theory that the Sumerians originated from the east and were perhaps of some relation to peoples of ancient India, but it is only a theory and has not been developed much yet.
Cormac can correct me if I'm wrong, but I believe there's also something in the genetic record to suggest as eastward origin for Sumerians. I recall some discussion about that a long time ago here at UM but can't recall the particulars. It may have been more to do with the general population of that whole region.
The next civilization to emerge was the Egyptians, and there is no doubt that theirs was an African origin. While the people who created dynastic Egypt were a mixture of ethnicities, I know of no research connecting them with any sort of European origin.
All the others were asking for was a source for your information. It's something I frequently ask of posters, too. It's good to defend your position and share your source for evaluation by other posters. If the source is flawed, so be it. If it turns out to be of some veracity, it will do us all good to evaluate. Was it perhaps one of those Russian websites about which I issued a cautionary note?
I tell ya, for all the Russians have contributed to science and historical studies, they seem to unleash a lot of wackos on the internet. Like I said, I've seen quite a few nut-job Russian web pages posters have sourced at UM. Methinks they imbibed in too much vodka (the Russians, not the posters, although who can tell?).
