It looks like they are both conspiracy nuts who believe that the entire world history up to some point is an elaborate forgery. Fomenko seems to believe that it was done to suppress knowledge about the Russian empire, while the creator of the videos above seems to believe that everything up to modern history is a forgery and that it was done to obscure the truth of Noah's flood.

The reasons why they believe these things are also different - I haven't read Fomenko, but the videos above seem to focus on a belief that oldish-looking buildings can't be relatively new (they know this becaude they can't find examples of large oldish-looking buildings being built literally today in their area) , so they must have all been dug up from a much more advanced prior civilization, after they had been buried by the flood of Noah.
