That's a fair and interesting point. However, post-flood we once again sprang from the Caususes. Thus our racial name. Finding history before then gets really hard. Best I've been able to determine is that the root peoples of the Scythians has civiliazation dating back perhaps as far as 28,000 years ago. We were in fact global, as is obvious from the swasticka presence globally in every culture in which we provided technology, agroculture, and law. But it doesn't tell us from where we originate prior to the flood. So while I accept your important distinction, I don't know what to do with it as I can't speak to it with others.
