How is a fact different from belief and truth?

Facts are very different from beliefs and truths. Facts are proven using facts and evidence to back up your claim. Truths can be different for everyone, because what’s true for someone could be untrue for someone else. Beliefs are what you believe is true or untrue. Beliefs and truths can change due to what you learn or know. Facts can’t change, because facts are backed up by evidence, not beliefs. Facts differ from beliefs and truths because people may believe in different things, but they can’t change facts. Facts are facts, they exist, it is reality.
