A scientific fact is a verified event that people may agree on. Whether or not others agreed with me, if I observed what was going on in the world around me using my five senses or my sixth sense from out of the body, this would be considered factual. If I claim that the world is a particular way because it is how I perceive things, then this is an opinion. For a fact to be scientific, it must be testable, observable, and repeatable.
