Sure, but what do you believe?
Being Orthodox Christian I believe only in God. All pther things I know.
Show how there were Russians 4500 years ago. Your claim. You show the evidence.
Read all tons of anthropologists and archaeologists studies, along with historical chronicles, including Western ones like "Letter of Alexander III of Macedon on the Slavic people". Somebody banned you from that info? Or it is all banned by BigBrother on the West to not disturb peasants minds? Or may be it is only Jews allowed to have long history of existence on the West now?
Why you are so incurious? Why do you think all other people have to believe in some info like you do, instead of knowing facts? Fascinating, how screwed and servile your way of getting info about world around. You used to believe in what you was told, and can't explore the world by yourself. I'm sorry for what your government did with once great nation of explorers and inventors.
