Philosophy asks questions about the meaning of existence. Perhaps the most basic question in philosophy is: what is the meaning of existence? But you always assume that the meaning of existence is obvious and invariable, and proceed from that point, as if the whole matter is settled. Where's your sense of wonder?
As regards the robust defense of the common-sense view of life, if common sense is the ultimate reference point for experience, why ask philosophical questions at all? If the world simply is as everyone sees it, what is the point of philosophizing?

It is not possible to conceive of it, or consider anything, from 'no' viewpoint. For an object's existence to be at all meaningful, it has to be considered from a viewpoint. As to whether it exists or has properties external to all viewpoints, this, I believe, is what Kant declared forever unknowable, so you can take issue with that if you wish.
Whether and how the Universe, or even the simplest object in it - and there are no completely simple objects - exists, in the absence of perception of it, is an assumption, an inference, and an act of faith. Of course things don't go in and out of existence whenever they are not looked at. But their existence 'as they are in themselves' must always be conjectural or inferential.
I think the reason this is offensive to common sense, is that common sense views the visible universe as the sole reality, and forgets to take into account the role, action and nature of that to which the visible universe appears. But common sense is foolish in this matter, because it is forgetting it real nature, or anyway, its true master. And this is simply a sign of the times.
Consider that the very most complex object we know of is the brain, which has more neural connections than there are stars in the known universe. This organ has evolved through billions of years, and is ultimately itself formed from stardust. The inherent logic by which the universe is itself organised has also given rise to this, and to us. The fact that the universe is so beautifully arrayed ought not to be cause of contention, but only appreciation. The mind and nature itself are co-extensive. The heavens contain many wonders, it is not just all dumb stuff.
Go read some Emerson, for heaven's sake, and stop sticking up for such a stodgy argument. Over and out.
