Direct evidence is evidence which, if believed, proves the existence of the fact in issue without inference or presumption. It is evidence which comes from one who speaks directly of his or her own knowledge on the main or ultimate fact to be proved, or who saw or heard the factual matters which are the subject of the testimony. It is not necessary that this direct knowledge be gained through the senses of sight and hearing alone, but it may be obtained from any of the senses through which outside knowledge is acquired, including the senses of touch or pain.
