Author did leave us some info (that earth did have a real "God" creator who came back to earth, humans got scared = war, humans lost, earth became different, gods rose or came back to rule here, as some aliens did too then so on) but they were in separate chapters so it's hard to go back to them for reference. Hope author considers making a breakdown or like a family tree of the gods and creatures here.
Im.curious about this world building. It lack details for me. Its intriguing but the story did not explain further
