Evidence is information or objects used to prove or disprove a fact in a court of law. Evidence is a critical part of legal proceedings, as it helps determine the outcome of a case. There are two main types of evidence: direct and circumstantial. Direct evidence is direct proof of a fact, such as an eyewitness testimony. Circumstantial evidence, on the other hand, is indirect evidence that provides an inference to a fact, such as an inference from a pattern of behavior. Other types of evidence include documentary evidence, scientific evidence, physical evidence, and demonstrative evidence. Documentary evidence is evidence that is in written form, such as letters, emails, and contracts. Scientific evidence is evidence that uses scientific methods, such as a DNA test or blood analysis. Physical evidence is tangible objects that are used to prove a fact, such as a weapon used in a crime. Demonstrative evidence is evidence that is used to explain or demonstrate a fact, such as a model or diagram.
