Yes, once you no longer trust authority and have to find the truth for yourself it becomes difficult to determine historical reality

I think the strongest evidence of human lunar landing is not grainy video or astronaut testimony but retroreflectors because they can be tested now - unfortunately these tests pick up something like 1 photon of return signal and false positives are possible (and even the official narrative includes Soviet unmanned craft putting retroreflectors on the moon)

So it's probably best to say I don't know, I don't see any way that I could know for sure, and frankly it doesn't affect my life one way or the other

On the other hand I have pretty strong confidence that some "foods" are toxic and some "unhealthy" foods are healthy, and this does affect my life.

Even more extreme are the cases in which state officials and "journalists" present ideas which are not false but incoherent, like paper money or trans women. These two share the distinction of substituting our perception of a thing for the thing itself - a common inversion
