Yup. Evidence is a precondition for knowledge, or maybe even causes
knowledge. That is different from saying that evidence and knowledge
are synonymous.
Indeed, if A and B are synonymous, then A does not cause B and B does
not cause A That's because you can always replace synonymous terms for
each other.
Assume that A causes B,
Assume furthermore that and B are synonymous.
From this it would logically follow that A causes A (because you can
always replace synonymous terms in a sentence for each other without
changing the truth value of the sentence)
But there is no such thing as self-causation, A never causes A.
Hence, If A causes B, then A cannot be synonymous with B

Indeed. And the same analysis as above applies. Here too evidence is
cited as support for a knowledge claim - which means that they are not
synonymous

Not sure what you mean with that. In any case, in none of these examples
are evidence and knowledge used synonymous. Indeed, they are all
perfect illustrations that the terms are not synonymous.

The problem is not your use of the word "reality", your problem is your
use of the word "define" and "synonym". Experience is one way n which
knowledge claims can be justified. That means experience can be a part
of the definition of knowledge (in the definition I gave, as one form of
justification) but that's all.

yup. knowledge is based on evidence. Which means that evidence and
knowledge can't be synonymous, since a term can't be based on a
synonymous one - that would be a tautology.

Possibly. I might have been ridiculously generous. You use the term a
lot, but I can't remember a single post where you do it correctly. So
getting it wrong ten times out of ten might be closer to the truth,

See, another example of you not understanding what synonymous means.
"Being synonymous" is a relation between terms or words, that is
linguistic entities.
"Being based on" is a relation between objects (which can include
processes etc)
So they are different categories to start with.
The logical form for "Evidence is based on knowledge" in first order
modal logic would be something like
"K(x) -> nec(E(x))"
(If you know something, you must have evidence for it)
The logic form for "Evidence and Knowledge are synonymous" would be
nec(K(x) <-> E(x))
(It is necessarily the case that whenever you know X, you have evidence
for X and if you have evidence for X, you know X)
two very different formula (admittedly, both are simplified a lot - you
need second order logic to to it properly, but they remain just as
different whatever formalism you chose)
In particular, "A is based on B" expresses a contingent truth (a fact
about the world), whereas "A is synonymous with B" expresses a necessary
truth (a statement about word meaning, not about the world)
