Yes, indeed!! Look at it all!! How much goes over your head???
The universe is a creation of High Intelligence. How much of it is not understood? How long did mankind watch birds fly and lightning strike before they had a clue of what they were looking at?
There is so much knowledge staring us all in the face, waiting to be Discovered. Is it all really in the box you have created for yourself to put it all in?
As much as you think you see it all, Look again for there is always much more to Discover. Why have you stopped looking? Do you really think you are done?
That's what I see. It's very clear!!
Why do you assume we have stopped looking? We have simply stopped looking for things with no evidence. But we are very actively searching for things we *do* have evidence for or where the evidence is inconclusive or where the interpretation is in doubt.
For example, we don't understand the formation of galaxies in detail. We don't understand the nature of dark matter or dark energy. We don't understand neutrinos. And the fact that we don't understand these means we probably don't understand a great deal more.
But to search does not mean you need to looks for dragons in a coffee cup. Nor do you need to search for elves inside of a computer. Being open minded doesn't mean you should let your brain fall out.
You like to say there is purpose everywhere. but what criteria distinguish whether something has a purpose or not? How can you tell if something *doesn't* have a purpose? Is there a test you can do?
The point is that this question is not unique to theology. it also appears when studying other cultures. We need to be able to distinguish those things that happen without human intervention from those that don't. And one of the better criteria is to search enough so that you understand what sorts of things *can* happen naturally, which things are *common* or *rare* naturally, and those things that are very unlikely to happen naturally. Then, we you find something, you can more easily determine whether human intervention is required.
A similar protocol should be adopted when searching for 'purpose'. We *know* somethings have apurpose because humans *give* them a purpose or construct them for a purpose. How can we distinguish those things from others that do not have a purpose? One basic criterion is whether something with a brain (like a human) made them to benefit themselves.
So, when we ask if the sun has a purpose, we don't ask whether it benefits *us*, but whether there is any other agent with a brain (or even consciousness) that is known to exist and had a goal of making the sun. The alternative is that the sun came about through purely natural means with no intelligent intervention.
When looked at in this way, it is clear that the sun came about without intelligent intervention: it is one star among hundreds of billions in our galaxy alone and is not special in any way that is obvious. the conclusion is that the sun has no purpose, even though it certainly benefits the domesticated primates that inhabit a small planet in orbit of the sun.
