This is exactly what I was asking.
Thank you SergeMak.

So the Slavs are a branch of the Indo-European peoples.
They were living as different tribes in an area where is the today Ukraine. From where they come from? From India? From Siberia?
One of these tribes were Russians, Ukrainians, Serbians, Bulgarians and etc. These tribes in the 6th century had different names? (i.e. the Russians, the Ukrainians, the Bulgarians etc were not called like this at that time)
They start immigrating as the map shows after the 6th to the different areas where today are the Slavic countries (e.g. Russia, Bulgaria, ex-Serbia etc).
Can I say with safety that before the 6th century Slavs didn't have any position to countries were they were living ancient tribes such as Celts, Romans and Greeks etc?
Their first formal state (i.e. something above tribe system) was the Древнерусское государство Русь or the Киевская Русь. From this state they start expanding until Vladivostok. Correct?

Three additional historical questions:
1. When historically Slavs formed a common alphabet based on the Greek alphabet?
2. When they become Christians?
3. When the tsars came in to power? (I think there are two dynasties).

P.S. The statements that I used to start this post don't belong to me. The belong to great philosophers such as Kuhn, Quine, Feyerabend etc and they describe the existence of scientific paradigms. This is a school of thought supported by the majority of scientists. Also the greatest philosophers of our time before relativists seem to support the school that: "what exists, that is true". Quine for bytemare who is asking said that paradigms cannot explain religions (and also that religion does not have anything to do with science.
Regarding the begining of WWII in 1937 I think that everyone disagrees except from that who say it. Based on my undersdanging WWII started in 1918 when the Versailles tready was signed (this is just an opinion. As I said opinions are respected but they don't make history).
