What's the difference between facts and truth?

Facts are pieces of information that are verifiable and based on empirical evidence whereas truth, although a related concept is related to a subjective perception or belief of what is a fact and does not always require evidence. An example would be a question about whether aliens exists. Many have a personal belief that aliens do exists, but since no empirical evidence exists upon which society can reach a consensus that they do truly exist. Someone may say that they are speaking truth when they say that aliens exists, however this is more likely just based on their belief which is unsupported by evidence (assuming in this example that the person making this statement has no empirical evidence). In this example someone who says they believe aliens do exist, believes they are speaking the truth but that does not make it a fact.
