"This argument is self-defeating . A theory is not a fact , no matter how much evidence may support the theory . Bad wording . But again , if you claim something as a fact , you must have proof , verified in both your method of reasoning , and the reasoning utilized by the person you are proving the fact to ."
"A fact is simply a phenomenon that is observable by any competent observer . It is not proven . For example , Euclid made the assumption that one and only one straight line exists between two points . This is generally considered a fact . However , two points that can not be connected by a straight line could be discovered tomorrow , and that Euclid 's first postulate would be disproven ."
