Abram was born in Ur, but God called him to a new land, which is now in the vicinity of Israel.
Abram was already considered a Hebrew at this time, as mentioned in Genesis 14:13.
Many Biblical scholars say this is derived from one of his ancestors name’s: Eber (Genesis 10:21). Note, that many people groups have multiple names to describe themselves, for example: Celtic, Irish or Scot, or by family surname. Abraham was born in Ur and was a descendant of the Eber family line.
The question about who is “indigenous” to Israel begs the question of how long must a people group live in an area to be considered “indigenous.” Abraham was there over 4000 years ago.
Jews obviously have a very strong historical right to the area now occupied by Israel, and the genetic evidence strengthens that right. I’m wondering if Abraham’s ancestors perhaps came from what is now Israel - that would explain the genetic evidence, and could also explain why God called him there - to return to his ancestral home.
I looked up the definition of “indigenous” and found this: “inhabiting or existing in a land from the earliest times or from before the arrival of colonists.”
Perhaps I’m being over-sensitive, but I see a racial - anti-white - connotation here. To take an example: America. It was populated in waves: initially from Asia, and subsequently from Europe. But the dividing line between indigenous and colonist is not between the first wave from Asia and all subsequent waves (irrespective of whether from Asia or Europe), but between the Asian waves and the European waves - in other words, based on race.
