I recall a former Freeper who was adamant that the English language had its roots and beginnings in ancient Hebrew. Ridiculous and easily refuted but no one could convince him otherwise.
It’s all part of that same “British Isrealism” nonsense from around 400 years ago.
At least back then they didn’t know anything about genetics. Today’s true believers in that fantasy have to ignore genetics as well as linguistics, culture, and the historical record.
When the Romans encountered the Celts and Britons the Druids weren’t speaking Hebrew nor writing anything down either.
