I seem to recall from school the phrase “cradle of civilisation”. And I’m fairly sure I read in Jared Diamond**. — still 20 years ago — that the climate was wetter in the middle east some 4000 years ago. The ease of creating an agricultural surplus enabled tribes in that zone to support extra people who did not till the fields. Kings, Judges, accountants. I’ve often felt sad that Persia /Iran is on such bad terms with the west
