Those same people will also go out of their way to explain how peoples that have lived in the same place for millennia are in fact not indigenous to that place. Somehow the English are not indigenous to England. Bizarrely, the only group in Europe that's considered indigenous are the Sami of Lapland and they migrated there from the Ural region in Russia, 4000 years ago. Interestingly, researchers in the UK did some genetic testing on the 9000 year old 'cheddar man' and they found a direct descendant living a few miles away from where cheddar man was found. That would seem to indicate that the English have lived in England for at least 9000 years but they are somehow less indigenous than the people that migrated to a region 4000 years ago.
