That’s not a “negative.”
They said nobody is shedding graphene. All one would need do is cite the credible evidence they obviously believe that makes their claim valid. In other words, that evidence that the persons with the graphene in their blood cannot shed graphene nanoparticles. Or prove it themselves with scientific reason.
You can easily prove you’re not dead.
You can prove at least some negatives. That’s not an absolute statement.
