LOL yes i have also read about UFOs, nephilims etc., the problem is that there are particular sources recognised as official.And if you tell to any serious scientist that there were slavs in balkans before 6th century he will be unable to stop laughing.Like it or not, this is the truth my friend, this is what all serious scholars and medieval sources prove.Slavs were settled in balkans in 6th century.there are thousands of sources to prove it, as well as all serious scholars, and not even one source to prove the opposite.
Only people with low education can believe such things.I don't speak russian however i can imagine what this illusionist writes there (LOL the really funny is that these people that 3.000 years ago called themselves thracians illyrians greeks etc. couldn't even imagine that in 21st century a few illusionists will change their nationalities and the whole history)
