"The important caveat is : 'boundaries around where concentrations of unusually high probability density lie, to the best of our knowledge and belief' ."

I would call the above an instance of the Mind Projection Fallacy, as you seem to be assuming a probability density that is a property of the physical world, and which we are trying to ascertain. But probabilities are properties of our minds (or ideal, perfectly rational minds), not of the exterior world, and a probability distribution is simply an entity to describe our state of information; it is "the best of our knowledge and belief".
