This doesn’t make sense to me. The presence or absence of evidence does not determine whether a fact exists or not. Evidence refers to the basis for a belief. There can be evidence for non-facts (e.g., opinions), as well as no evidence for facts (e.g., whether the nth heaviest dinosaur that ever existed was doing something that we expect there to be a 50% chance of it doing when it was exactly 1 year old).
