> if it isn't accessible by science it isn't reality, it's delusion.

That's a terrible philosophical outlook. It is to be ridiculed as much as flat Earthers. Who argues that nonsense?

> Science does say: "This is true to the best of our knowledge."

No, it doesn't. It says here's the model that best fits the observations we have. Nothing to do with truth, and not even relevant, to what I said, profound truths. It makes no metaphysical claims, no ontological claims, requires a philosophical model for its limited epistemic claims, and it says nothing about the human experience as such. It doesn't answer as to the essence of humans, as to the very experience of reality, as to the nature of reality, as to the source of reality, as to morality, as to meaning, and so on. Science is useful only in its limited practical scope, nothing more.
