There are several types of evidence that may be used in a court setting. Evidence can be direct or circumstantial. Direct evidence is the items in a court case that can be seen or certain types of eyewitness testimony. Circumstantial evidence is usually a series of events or characterization that implies guilt. All the facts that are collected for a court case are tied together to help a judge or jury make a decision to convict or not to convict someone on trial.
Evidence, broadly construed, is anything presented in support of an assertion. This support may be strong or weak. The strongest type of evidence is that which provides direct proof of the truth of an assertion. At the other extreme is evidence that is merely consistent with an assertion but does not rule out other, contradictory assertions, as in circumstantial evidence.
