To me it comes across as Zeus being likely an IS-BE of the "old empire" (the guys that built the Death Traps here long ages ago and who were eventually thrown down and then The Domain moved in to our local area. Were the Anunnaki one of these sides or another altogether--do we know yet?) Is Zeus an agent of the "old empire"? Because his origins seem human in Egypt, and then later in Rome or the Middle East as a leader, but still under the thumb and directive of higher authorities ("old empire" holdouts or was this happening before The Domain came and wiped them out of the Sol system?) He's also part of carpet-bombing as well, in one of the ships doing it, right? ('The Asshole' = Zeus? Must be.)
Then we see him possibly as a non-corporeal IS-BE controlling one of the bombing craft or perhaps just blocking that viewer, because we also see "The Asshole" on another ship doing more bombing campaigns.
But it sure seems like Egypt with the pyramids for some part of it, the inter-connectedness of them, and the energetic sky-display when they were completed (but wasn't it the grays that showed up and did the repeated plagues and famines until everyone left Egypt?)
Lastly the death-star like ships make me think of the Reptilian Bird-Of-Prey style ship. But, simply coincidence?
Lastly, the cannons firing up at the bombing craft were interesting, so either the event wasn't that long ago (but you'd think there would be more stories about firing up at bombing craft), or perhaps was it during a former era of civilization that has vanished resulting of catastrophe?
