I think by "something" he means "phenomenon" and by "re-creating" he means "observing". So I think he is saying: if it is claimed that phenomenon X exists but there is no way to ever observe it for entity Y then X doesn't exists for Y.

But I'm not sure, it's my interpretation. The write-up resonates with me but I can see it as a bit ambiguous and inviting many incompatible interpretations.

Proper treatment of the subject in a book format would be great.
