The Theory of Factual Evidence states that theories can be proven true if a sufficient amount of factual evidence is provided. All ways of proof involve the assumption that this theory is true. Despite the importance of this theory (without it, nothing could be proven), it has yet to be proven correct.
Primary Evidence. An authentic document or item that is offered as proof in a lawsuit, as contrasted with a copy of, or substitute for, the original. Primary evidence, more commonly known as best evidence, is the best available substantiation of the existence of an object because it is the actual item. It differs from secondary evidence, which is a copy of, or substitute for, the original. If primary evidence is available to a party, that person must offer it as evidence.
