Strawman and projection, as you are conflating necessary and sufficient.
As if something that exists and occurs (belief) is necessary in order to make something else (the truth and reality) known to exist and occur, then that something's mere necessity must be sufficient in order to make the truth and reality known to us. And like I have already shown; if justified true beliefs are still beliefs in reality, then it must be beliefs necessity that makes the truth and reality known.
Not true, as I seen bread without flour. So, flour isn't necessary in order to get bread.
If belief is necessary in order to make the truth known and the truth is unknowable without belief, then your analogy is inapplicable, because there exists breads that don't require flour. But there isn't any knowledge of the truth and reality without belief, a matter of fact justified true beliefs are defined as knowledge of the truth and reality. So, it is belief's occurrence in reality that makes the truth known or knowledge, so reality is the result of a believing mind, because the truth and reality can't be known to exist or occur anywhere else but in and with a believing mind.
But if you think that the truth and reality can be known to exist and occur outside or without a believing mind, then say what that other way, place or thing is that isn't a believing mind and explain how it makes the truth and reality known to exist and occur?
