You claim that you know that something that can't be measured does exist. If you haven't just made up that claim, that implies that you have somehow detected the existence of that thing. What you might not be aware of is that in the eyes of a scientist that makes you into a "measuring apparatus" for the thing that you claim cannot be measured. In order for a scientist to consider something unmeasurable, it cannot have any influence on the natural world, as that would be a measurable effect. Making you utter or type a claim about the existence of something is an influence on the natural world that can be measured, so if you making that claim is actually causally connected to the thing (as opposed to made up by you), that would make the thing measurable.
