in my opinion we really need a RUSSIAn nation but what tribes lived up there?

Sarmatians and Scythians across much of southern Russia and Ukraine, some Celts on the Dniepr (of whom we know nearly nothing), Greeks in the Crimea and Uralic tribes in Northern Russia (for whom we have no historical data, only archaeological).
