Well, how you interpret whether or not what we don't know will occur next can still be considered a fact depends on your core worldview (e.g., compatibilism, deterministic, fatalistic, etc.).

I subscribe to the belief that there are four types of knowledge and beliefs: ontological subjectivity, ontological objectivity, epistemological subjectivity, and epistemological objectivity. Various thoughts can be categorized into each one of these depending on what is being expressed.
