You keep coming back to the same WRONG question. You must UNASK the question
before you can progress (shades of Zen and R. Hofstadter).
The question you should be asking is: what do true and false have to do with the
world we inhabit?
Hint: the answer is the same as for your question: nothing.

What evidence? That hopes and dreams have something to do with true or false? Or
that true and false have something to do with the world around us? -- I see no
evidence for either.
I certainly do see evidence that (for example) Newtonian mechanics is an
accurate model of the world I observe in everyday life. But that has nothing
whatsoever to do with "is Newtonian mechanics true?" -- true and false don't
apply; NM is _VALID_ in the domain of our everyday lives. And it is not valid in
the domain of elementary particle physics (I see LOTS of evidence of that, too,
as that is the field of physics in which I make my livelihood).

Nonsense. I certainly do read about mathematical proofs, but only within their
domain, which does not include the world we inhabit. Theories and models of
physics certainly do involve mathematical proofs; but their relationship to the
world DOES NOT.

You have not been listening. I cannot "prove" that, BECAUSE PROOF IS IRRELEVANT
TO THE WORLD WE INHABIT. I do indeed OBSERVE, and therefore KNOW, that at that
place and time, thus-and-so happened. But there is no "proof" involved.
Proof is a mathematical and logical deduction of some proposition,
starting from clearly defined axioms. It only applies when the
quantities appearing the the proposition actually satisfy the
axioms. In the real world a) we have no idea what the axioms ought
to be, and b) it is QUITE clear that for any set of axioms the
objects in the world satisfy them at best approximately. And, of
course, objects in the world behave according to how nature
make them behave, not according to any axioms or deductions some
human might make up.
I repeat: you have it BACKWARDS: we humans make models of how nature behaves;
there is no constraint on nature to behave according to our models.

I'll stipulate that it does. Still, it has NOTHING WHATSOEVER to do with how
nature behaves, except being at best a MODEL of how nature behaves in some
limited domain (limited by the domain of validity of your axioms and your
deductive process).

Not really. If someone claimed that by simply flapping our arms we humans could
fly to the moon, would you bother to spend time listening to his arguments? What
you are trying to do is equally impossible. But YOU simply are unable to see the
complete dissociation between math and logic on one hand, and the world we
inhabit on the other.
Here are some relationships having the same basic structure:
logic : world [#]
map : territory [@]
model : world (aka theory : world)
knowing : doing
understanding : being
There is of course a pattern here: on the left are mental constructs,
and on the right are aspects of the world we inhabit.
[#} I mean "logic" in the sense you use it; nobody else would
include this here.
[@] I use "map" in the mathematical sense; a paper street map is
merely a bunch of marks on paper, the map itself is the abstract
correspondence between those marks and the actual roads and streets.
It seems that you may well have derived some of the equations of our current
MODELS via your "logic". Well, and good, but that does not interest me. And does
not come close to living up to your claims.

You sure phrased that funny, using "true and false" in a place where they don't
really belong. Experiments either confirm or refute the predictions of any given
theory (as it applies to the experimental conditions). And as I keep saying,
this is not "proof", because that word means something completely different (see
above).

Yes. And you used it incorrectly. Again.
This is going nowhere. Goodbye.
