See, the fact that you refuse to give me specific sources tells me that you haven't actually done any research on the subject matter and instead are just going on gut feeling or high school history textbooks. Neither are particularly useful for history.
The most reference anyone else has given me is a decades-old book (with no name mentioned) and some fictional, uncited maps. Neither of which is particularly useful for history.
And, yes, I gave you specific sources, and told you exactly where to find them. Whether or not they werre good, that's still more sources than anyone else posted.
Regardless, that's irrelevant to the thread, I'm not *trying* to discuss old-world civilization and its origins.
