In the process of creating the backstory of my world, I came to a major roadblock. That roadblock is: why would the gods of my setting create a world for multiple species of sentient life?
Context: The seven gods, or Great Ones as they are called later on, were all collectively different alien races that existed light years from each other and were never close enough to interact. Then, a Lovecraftian abomination with the mind of a two year old comes along and starts munching on these races and many others. Most races die out, but the races that the seven come from each have one survivor that, through one way or another, has become a being of great power. But still weaker than the abomination that strolled past their section of reality.
After a centuries or two in shock and mourning, these seven beings, remnants of there respective species, encounter each other and after another few centuries of moping around and understanding each other. The seven decide to stop the being the killed there loved ones, i.e their species and launch what is basically a guerrilla campaign against the eldritch being that after aeons of fighting, eventually weakened the being enough that killing it seemed possible.
The issue is that why, during this time, they go off and create a fantasy world? Humans exist on this other world along with other races that have evolved on this world with the assistance of the seven. And further more, the seven have brought it upon themselves to teach the races both science and what is basically the magic of this setting.
My question is why?
As for the gods themselves, they are may have eldritch power but are still ultimately social creatures that need social interactions to stay healthy (although their health at this point is questionable).
EDIT: The Gods are also ultimately benevolent. Since the story is about the events of what happens after the child-like entite finds this world and gets pummelled by the gods while it also pummels the gods in return.
