It’s not genius. It’s bigger egos.
As civilization progressed, needs arose for more complex, organizational thinking: trade/tariffs, tax assessments/collections, calendar planning (agriculture), money/exchange. Certain groups were able to adapt to this new way of living ie indoors utilizing brain processing vs outdoor physical labor. After around 6-7k years, today we call them Jews. Change the name, destroy the race, and the same type of group(s) would (re)emerge yet again simply due to the demand placed upon the skills they deliver.
The fact that they were/are persecuted for their unique advantages created outside pressure which drove them further into tribal insularity, including coining such self serving phrases like 'chosen people'.
How crass of you. Disappointing.
