I don't claim to be an expert or have all the answers but I have looked at this Siberia video and found some things that I wanted to point out. Of course, you are free to have a different opinion than me and to come to your own conclusions. The original video has some edits in it, which create a red flag for me. I really don't know who to credit for the video but it may originally be from the youtube user TUNGUS FENOMEN.
