I must admit I have not studied the history of ancient Sumer before
there were people living there. I do know the rationale for
settling the region was because the soil was rich and suitable for
growing crops. But not being a geologist I really don't know.
What is soil like that has been covered by salt water right up to
the time settlers arrive?
