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.
Circumstantial evidence allows a trier of fact to infer that a fact exists. In criminal law, the inference is made by the trier of fact in order to support the truth of an assertion (of guilt or absence of guilt). Testimony can be direct evidence or it can be circumstantial. For instance, a witness saying that she saw a defendant stab a victim is providing direct evidence.
