As a general rule, it’s the job of the person who makes the claims to prove them true.
Not the job of the person who calls the claims nonsense to disprove them.
I can’t disprove the claim there’s an almighty invisible sky fairy living in the heavens.
But I still call the claim nonsense anyway.
I'm sure someone has tweeted about it. That counts as solid proof these days. If it's got emojis and/or memes that's basically peer-reviewed.
