I think of it this way: We are already running simulations of the universe with very simple models. Imagine 1000 years from now what type of models we could be using. Perhaps models where every known law of physics is precisely modeled. Then let it run from Big Bang and fast forward 14 billion years. Maybe the simulation would create some lifeforms. Even if that was not the intention. If that's not too far a stretch then maybe some civilization exists where their top notch model will create the world we experience. Maybe they don't care or aren't aware that the simulation simulate life. Maybe they just care about how the universe evolves, and we are a biproduct of that.
