The "theory" of evolution is the same thing. We have no "proof" of it. But of course we do. Evidence is all around us, being evaluated in a multitude of ways by a multitude of people using different sources of data making similar conclusions supported by experiments and evidence. This is basically how we define "fact".
Of course somebody may stumble onto something that blows the whole equation up, but barring that, we have sufficient confidence to say it's fact. Granted the big bang theory is harder to observe, study, and experiment. Doesn't change how it's viewed by science.
(TFA opens with this. It suggests the possibility of something that may blow up the equation. Great. Similarly, if somebody can find something that disproves evolution that would be pretty ground-breaking, but the more established a fact, the higher the burden of proof.)
