Are you promoting radical scepticism and believe we should abjure from pro or con cases or are you a believer? They're not the same. Do you apply the same criterion to all rebuttals or only rebuttals of this kind? How topic specific is your concern with credibility ? And, forgive me but why should we care about your opinion over others?
You are in some ways invoking appeal to authority but then... All debunking is at some level an appeal to authority. I am unquestionably promoting an appeal to authority above btw.
Since there's no point discussing this "evidence" with a believer, I ask what you would consider viable credible discrediting. My suspicion is, no discrediting would meet your standard and you are not actually prepared to accept any alternate basis, such as lens flare.
