"Scholar" said : " all of the population had left Judah leaving the Land desolate for a fixed period of 70 years until they returned home 70 years later"
Archaeology clearly shows the land of Judah was NOT left without population during this period. Occupation and farming continued.

Archaeology at the moment is rather open to the nature of the Land whether it was fully deserted or unoccupied as the Bible explicitly states or that it was populated to some degree. However, it is what the Bible says that overrules the opinions of archaeologists which are built on 'shifting sands'.
The said scholar is very much aware of the matter as he has completed a short online course under the tutelage of Prof. Obed Lipschits who authored The Fall and Rise of Jerusalem -Judah under Babylonian Rule, 2013,Eisenbraums which was the principal textbook for this course. The said scholar received a Certificate for this course.
