The sun rose today is a fact only if you can prove it. I think you're crazy everyone knows the sun just appeared out of nowhere.

PS: Your aunt Sally called, she misses you.

No, facts are facts even if no one can prove it. It's just that if you can't prove it, you can't know if a certain claim (like "the sun rose today") is actually a fact or not.

I'm having trouble with this.

Can you prove that what you said is a fact?

Nope.

I think what icebraining was trying to say is: A fact is not a opinion that is proven to be true. A fact is a opinion that is true and can be proven to be true even if we don't yet know how. In which case we simply don't yet know that said opinion is a fact.

I'm not sure if this definition is correct but I'm fairly certain this is what icebraining meant.
