Evidence is and includes everything that is used to reveal and determine the truth, and therefore is presumed to be true and related to a case. Giving or procuring evidence is the process of using those things that are either (a) presumed to be true, or (b) were in fact proven to be true by earlier evidence (truths) and demonstrates the broadening of the truth of a case. And the collection of evidence is in fact the act of determining; what is evidence.
