Direct evidence is evidence that proves a certain fact without the need for any inference or deduction. It is the type of evidence that speaks for itself, such as eyewitness testimony, DNA evidence, or a video recording. Circumstantial evidence, on the other hand, is evidence of facts from which we can infer a certain fact. This type of evidence is more indirect and requires an inference or deduction to be made in order to determine the truth of the matter. Examples of circumstantial evidence include motive, opportunity, and behavior. There are several types of circumstantial evidence, including indirect evidence, presumptive evidence, documentary evidence, and real evidence. Indirect evidence is evidence that does not directly prove a certain fact, but can be used to support an inference or conclusion. Presumptive evidence is evidence that is presumed to be true until it is disproved. Documentary evidence is evidence that is written down or recorded in some way, such as a contract or a transcript. Finally, real evidence is physical evidence, such as a weapon or a piece of clothing.
