By the way the brain produces high fidelity illusions for us most

very different from the intermittent stream of neural signals that

you shift your eyes from one focus point to another that during the
period of time the eyeball is in movement from one focus to the
next no visual signals are being sent down the optic nerve. That if
the brain was not producing an illusion for us the world we see
should vanish each time we move our eyes (or blink them) Does the
world disappear each time you blink or move your eyes? Of course it
doesn't. Your mind maintains a steady and beautifully rendered
illusion of the world in your mind that is seamlessly stitched into
the new stream of optic signals as they arrive. There is no
discontinuity.
That seems to look at it the wrong way around. Our model of the
world is one in which objects are persistent even when we don't look
at them.
Even more! Today we have good evidences that when we don't look at
something (so that we are isolated from it), not only it exists, but
it multiplies. (cf. Everett, and/or Computationalism)
That's a better model than one in which they only exist when we look
at them. So our brain is creating the better model instead of the
worse. I see no reason to call that an "illusion".
We cannot know, we can only prey we have a better model, and that our
children will find even better model, and that such thing the model(s)
or reality/realities exist(s).
In all case there is some amount of faith, but it is coming from
inside, not from the books or talks.
Of course all authoritative institutional "religion" will always try
to discourage or kill that sort of faith.
I have faith and trust in elementary arithmetic, and other elementary
mathematical jewels.

When you turn your head from one side to the other does the world
spin? -- the world around you is instead held in a majestic
stability that is not real, because it should be instead spinning
as your head spins. Instead in our perception the world stays
stable and it is our "perspective" -- our inner view -- that
shifts. This makes sense from the point of view of the inner
observer, but the mind needs to do a lot of work to build the
illusion.
Our brains are, grand masters of illusion and we live in illusion
(a reification of sensorial reality) all our waking lives.
The perfection of our visual illusion is a masterpiece of
interpretive processing where the raw signals we get are stitched
together into a field of view and a focus within that field of view
that -- though it clearly is reflective of our sensorial reality is
also quite different; the "world" we see is very different than the
world as it is recorded on our eyeballs (even to the extent of
smoothly persisting without the barest hint of any interruption
even as our eyes are not seeing a single thing at all.
