Let me start by saying that I don't think we'll ever agree on this one ;)

Because that is what everybody does, even you. There will be things that
you believe are true to such extend that you don't see how anyone can
have a different opinion (either on evolution, the position of man and
women, gays, life, the moonlanding, some scientific theory, or whatever)
that are still disputed by some and considered part of your false religion.

Again that implies that you or somebody knows what is 'true'. I keep
repeating that there are many differences of opinion about what is true,
about what processes are allowed to determine if something is true and
all the other metalevels.

no, it is much older than written history.

Because nobody would say such a thing. Technically correct, but it would
raise eyebrows if used in ordinary conversation. 'I am confident this is
my daughter', 'No sir he could not have killed him, I am confident he
was home last night'.

Yes I was following your reasoning here, trying to point out leads to a
nonsense conclusion. I am confident that in e.g. Greek I would have used
another time than you did read.

No, he merely thinks it is true, he may be wrong, so he has to use
'believe' according to your rules.

yes. I know Newton's law of gravity. Now you may argue that we know it
is wrong but still can be used as approximation. OTOH that is also true
of almost any other important theory in physics.
I also know that most cardiologists know what causes the T wave part of
the ECG. I also know that they are wrong.
