RE: All facts are subjective

Can you give an example of a fact that is “natural principle”, i.e. that isn’t subjective? I’ve had this discussions with hundreds of people and so far no one has ever yet been able to present an example of something known that isn’t known by some set of knowers and thus dependent on their cognition of it, nor of anything that they can demonstrate conclusively exists in the objective world exactly as people imagine it does. And generally it is pretty easy to show how knowledge is a model of what is, rather than what actually is, so I’m curious to see what you have to offer.
