But how about the eastern part of the story - the Finns fleeing an Asiatic invader? Could it be, as well, based on real history visible to us today via DNA studies? Turns out, yes!
It has come lately to this author's awareness that back in 2018 a DNA study was done to exactly see at which historical point in time an ancient Asiatic genetic influence came to Finnish genetics. The dating is, as per the study, is:
That's c. 2104 BC to 1950 BC - an astonishing match with Oera Linda book narrative where the Finns conquer Scandinavia at c. 2093 BC, driven behind by another people.we estimate the time of introduction of the Siberian Nganasan-related ancestry in Bolshoy [Kola Peninsula] to be 3977 (± 77) years before present (yBP) (Ancient Fennoscandian genomes reveal origin and spread of Siberian ancestry in Europe, p. 6)
Taken together with above mentioned Scandinavian DNA studies, how could previously assumed mid-1800s AD Dutch forgers could have gotten this right? For sceptics, to falsify this you would need to show how presumed mid-1800s AD Dutch would have known this level of detail right. Note that the Asiatic driving force for Finns is not present in known Norse, Sumerian or Biblical echoes - it's only explicitly mentioned (correctly) in the Frisian Oera Linda version.
As secondary implication, these DNA results taken along with the Sumerian clay tablet echoes mean that the 2104 BC dating is exactly correct - there really was that much of time in years. However, this does not mean there couldn't be textual forgeries as to data filling those years in various chronologies. E.g. more or less same ruling lengths for various dynasties, implying massive copy-and-paste jobs to fill-in missed biographical data, as opposed to old authors doing every single time the hard work of calculating the biographical dates retroactively via astronomical means (which would have often resulted in bizarre middle-of-night dates for various happenings, as Russian researcher Fomenko correctly pointed out).
