I'll speak from three angles. From my former Christian days (I did in fact get a theological education), I would say that Christian theologians don't really have a good answer to this question. But, the angle from which you took it (that the world was too boring), is definitely one that is posited by some Christian minds within that sphere. I honestly don't think this question is brought up as much among theologians as, say, Arminianism versus Calvinism, especially regarding free will, or the debates about the origins of creation (aka, is evolution true or is creationism?), or questions regarding salvation etc (I grew up in a rather strict theological environment, so there's that). And, of course, the most frequent discussions regarding anything like the question your positing are more about debates of the purpose of evil and hell, etc, This is only of course, from what I can remember.
Now, from the time when I was Agnostic, well, Agnostics view things as solid in the scientific world, but with some mystery, so I would say that question, they would probably say if there is a god, how could we possibly know what it was thinking.
And, of course, lastly, my view of it all from being a modern Pagan. The thing to keep in mind about modern Paganism is that it is first of all, a DIY religion, meaning you figure out your own theology as you go and from personal experience, plus whatever you can pull up from ancient cultures especially in the European and Middle Eastern arenas. Within that theology, I would say there is a right leaning path and a left leaning path. The left leaning path is more New Ageish, but not always. Anyway, they include things like Wicca or Eclectic. The right leaning path are those that are reconstructionists (sometimes they do not like to be referred to as Pagan). These are individuals trying to piece together ancient religious practices in very specific locales in Europe, mainly. Asatru and Hellenism would be examples of this. On top of this, I would add a third category, the groups that are kind of in between right and left. I would include Druidism in this, because although they are often reconstructionist to some extent, it seems like they go either way, and I'd also include a new branch of Paganism called Reform Paganism in this category as well (this is the branch I currently identify with best, they actually incorporate transhumanism and technological acceptance into their paradigm to some extent, very young yet though). As you can see, with all the amount of diversity out there in terms of modern Paganism (really just an umbrella term for a bunch of tiny religions or spiritual practices), narrowing down what we believe is the purpose of the universe would be impossible. But, I would argue, no matter what one believes, that would be kind of an impossible question to truly answer. My own beliefs do sort of have an answer though. See, I think this whole progression of the kardashev scale has happened many times before, in other universes. And, the weird belief I have is that, once you get to a certain level on the kardashev scale, you try to get to another universe, and find that the laws in place in this universe are unbreakable in that regard, then you try to hack into the system (I believe there is a system of energy (spiritual energy) that connects everything and minds as well), When you find you can't do that either, you either let yourself still be part of the system and whatever happens, happens, or you create another universe to exist in for fear of death or the end of the universe. So, essentially, I believe we are in a universe which is in a universe, which is in a universe, which is in a universe, etc. Where the originals came from, or how they were created or came to be, that I don't know. I also don't know what happens to the other universes if a universe is destroyed (maybe it can't be?), so there are a lot of issues or questions in that regard. As far as the gods go (I know you are talking from a monotheistic viewpoint, but in my viewpoint, the system, the Universal Mind, doesn't really engage with people that much except for to deliver messages or energy), I believe they are more advanced minds on the network here to help us also advance. Whether they are all from this universe or another I don't know. My view of the universe is kind of more complex in another way. I believe that there might be a multiverse, and multiple dimensions, and a "mirror world" which I call the Other Side, that is the spiritual world. It has it's own set of laws physically like we do, which is why there is not much true scientific evidence for it (due to restrictions). Our bodies are simply Avatars for our soul, and we can have many lifetimes if we so choose, or if there is a lesson to be learnt, etc, etc. Yeah, my views are absolutely bizarre and they are also absolutely complicated. I was trying to account for in my theology the personal experiences of people with near death experiences that are all different and interact with different spiritual realities, so I tried to unify theologies as much as I possibly could to encompass different perspectives. This is why I believe the Other Side actually has different realms. Anyway....sorry if cause no one else to comment. Lol! My comments tend to have a deadening effect it seems.
