I believe we had this discussion before and you're just as mistaken now as you were then. Evidence is facts. Given enough facts you come to conclude Oswald did kill the president but it doesn't become a fact he killed the president. It may achieve to be a belief beyond reasonable doubt. Facts themselves are beliefs held to be true unless some new evidence usurps it. On the other hand truth is whats actually true whether anyone believes it, no one believes it or whether any facts support it.
"the available body of facts or information indicating whether a belief or proposition is true or valid."
See I think you are confused because belief is in the definition.
How ever if you read it carefully you will see that evidence IS the facts or information, (Indicating) (now follow along here "Indicating" is a verb,I hope I don't need to explain the English language to you.) whether a belief is true or not.
So you see evidence is what proves a belief and not the belief its self.
It seems like you don't fully understand the definitions of the words you are using.
Also facts are not beliefs. Once something becomes a fact it's no longer a belief.
