The Phys.org article paints a much more clear picture:

> More specifically, the researchers found evidence of several efforts that together over time, added up to a completed structure. The first consisted of sculpted lava—where builders had carved shapes onto the top of a small, dead volcano. Then, several thousand years later, sometime between 7900 to 6100 BCE, another group added a layer of bricks and rock columns. Some unknown time later, another group added a dirt layer to part of the hill, covering some of the earlier work. Then sometime between 2000 and 1100 BCE yet another group added more top soil, stone terracing, and other elements.

> The research team has also found some evidence suggesting there might be some hollow parts inside the structure, suggesting possible hidden chambers. They plan to drill down to them and then lower a camera to see what might be in these areas.
