So Abraham could have see some of the destruction of the Sumerian cities>>>>>>>>>>>>
I agree, the damage was so horrid that large areas would have been very much like Hiroshima and Nagasaki afterwards. This kind of damage would have been visible for hundreds of years if not longer. Whole cities disappeared leaving only the imprint of their foundations.
Abaraham’s era would have been post apocalyptic.Indeed Yaweh showed the Jewish people where they needed to travel to avoid the sickness associated with these poisoned areas.
Certainly would have made an impression....”Never Anger Yahweh!....or as Psalm 2 states...”kiss the Son lest you perish before he has gotten just a little angry”
