No one questions the existence of stones. They are ubiquitous. We throw them. We stumble over them. They crack our windscreens. We build castles, and walls, and roads from them. There is abundant evidence that stones are in fact real.
The question “how did this particular stone get here?” is another thing entirely. The existence of stones is assumed in the question.
There is piss-all evidence for ghosts. Full stop. Just as there is piss-all evidence for any other imaginary creature one might care to mention. Until the first shred of evidence for the existence of ghosts is offered, “ghosts do not exist” is a perfectly proper response to the question “Is this a picture of a ghost?” Or, to put it another way, “Is this a picture of a what?” is a perfectly proper response.
“Is this a picture of a ghost” is the one that begs the question, because it assumes, absent any verifiable data, that ghosts exist.
Define “ghost.” Mount some reasonable argument that ghosts exist. Then, and ony then, can we attempt to answer the question.

The reality of stones is not the point; the origin of stones is not the point; the structure of the argument is the point.
Well, of course there is piss-all evidence for ghosts when the assumption is made that all evidence of ghosts must be fabricated because ghosts to not exist.
No, asking if an artifact is evidence of a thing does not presuppose the thing exist; the asking only allows the possibility that the thing exists. Basic scientific inquiry.
The best argument for the existence of ghosts is that so many people have had a ‘ghostly’ experience; in a perfectly unscientific experiment lasting several decades, I have been asking people if they have ever directly experienced a phenomenum inexplicable by current scientific theories (in much less pretentious terminology). The answer is almost alway ‘No … except this once …’
I think I am the only person I know who has never experienced a ghost; so there is no way I will be arrogant enough to insist they do not exist.
