That makes sense and I agree with the changes in Iran would make it one of the youngest. Not sure of cultural changes through the AD time period. 3000 BCE is the stat for Iran “beginning”, that’s a long ass time lol.

I agree though, and it’s almost an impossible question to answer because every country has gone through cultural changes.

I would say a better answer would be the Sentinelese people on North Sentinel Island. Untouched culture and isolation from the rest of the modern world for 60k years.
