One of the reasons I find this questionable is that a quick overview of the site (this is not a location where I'm familiar with the archaeology or culture) says that the land surface is artificial islands. If it was dry land, there'd be no need to construct a bunch of hills for structures to sit on.

IMHO, of course.
