I look at the universe like this: Some things are unanswered, some things are known, others might simply be axioms.
It's very tempting for us to think that everything has a reason, and underlying principal behind it. Some sort of purpose for it. Nearly everything does, and I think it is good practice to assume that everything does. In the realm of understanding the universe, this is required. It's how we push boundaries and learn. Honestly though? I sometimes wonder if there are some thing that truly don't have answer, because
that is just how it is. It's sort of uncomfortable to think about. How could something that is a fundamental have no reason? It's a possibility one should consider though, among all the others. It's something many Ni-doms in particular don't want to do, but it doesn't make it any less valid.
I have nothing to go by, and this is pure speculation on my end. Ultimately, science will have to find the answer (or lack of). That said, I wonder if the universe is actually timeless, and I mean that in a literal sense. It's possible that the universe has no beginning, and no ending. As such, it has always existed. It starts running into the concept of infinity which is really
hard to grasp, which is why some may not entertain the idea. It seems that we want the universe to be finite. Why does it have to be? It's reasonable to think it could be forever. If we assume the universe is a closed system, then there is a finite mass and energy, and it can be rearranged into infinite ways, and in effect "recycled". If the universe has always exsisted and always will exist, then the question of "why" might ultimately be moot. To some this might be woefully unsatisfying because it doesn't get to a "why" answer. To me though, I find the idea of the answer being that there is no answer, truly awe inspiring.
Of course there is the whole issues of the universe accelarating further away from itself, leading to "the big freeze", puts a bit of a small kink into the "forever idea".
It might not be afterall though. Theories are always evolving. In another 20 years our perspective of what the universe is could be completely different. When we learn more it might become more clear.
If you look at it from a totally objective point of view "we" are nothing more than the universe observing itself. We are all made of the same fundamental materials that goes through the universe. "We", the universe, have come together in such away as to gain awareness, and interact with itself. Saying that it is simpler to not have senses, isn't really fair. In some respects it is. We can all agree that we are more complex than a rock from a chemical standpoint. However, I'd argue that our senses are meerly incidental. Consider entropy (and to a minor extent enthalpy). All of our chemical reactions and processes are (overall) downhill processes. It might seem crazy for such a complex system to come together, but you can get some very amazing things to go forward simply by the process of going downhill energetically.
Not everyone seems to like this, but I consider many if not all things in the universe to be "incidental". To me though, that doesn't detract from any of it. In fact, it makes it even more interesting, and in a way it seems like a grand design of sorts afterall.
