Because the facts of the case exist objectively, the evidence to prove the facts of the case should also exist objectively. As evidence in litigation, it must be an objective fact. No matter physical evidence, documentary evidence or witness, fictional facts and statements made after speculation and hypothesis can be written as evidence.
