You already agreed that we can never objectively know anything. All we can do is make inferences by comparing our sense data and experiences with the reported experiences of others.
That which we experience directly deserves more credibility than that which we hear about from others, and we should ask others to provide evidence of their claims before WE assign any truth to their claims.
we can indeed know something objectively, but such an knowing is non-transferable, and hence in a way can be said to be subjective, as only the individual subject is able to experience it.
maybe even two or more people can come to objectively know the same object of knowledge, however, it's still subjective in their unique approach and expression/description of such.
also, if you say that what we experience directly deserves more credibility than what others experience; why would you go around asking for empirical proof of aliens, ghosts or souls?
who am I to judge BOG or anyone else in regards their direct experience of any such event?
that's the problem with all the pseudo-scientists trapped in Scientism, somehow they have fooled themselves into thinking that they themselves are the absolute point of reference, talk about narcissism...
