Absence of evidence isn’t evidence of absence.
“ Absence of evidence isn’t evidence of absence.”
Yes.
From the article:
“ At Mohenjo-daro, non-residential structures were built atop brick platforms that were as substantial as the structures erected on top of them, and would have required a great deal of coordinated action. It has been calculated that just one of the foundation platforms would have required 4 million days of labor, or 10,000 builders working for more than a year.”
That was just for one platform in one city. It’s only a matter of time before the huge serf/slave compounds are found, or some similar conscription of resident labor discovered.
