Do you have a line of reasoning for that? Models which take spacetime to be able to be warped, /to my understanding/, make what are currently the predictions which are most matched by experiment. I don't know why one would suppose that space and time do not exist, other than as some philosophical idea, but even if one does suppose that, it still appears to work well to model the universe as if they do exist. One would not expect a Berkeleyan Idealist to complain on every article about nuclear fusion because they do not believe that atoms exist. If space and time "do not exist", it seems like speaking of them as if they do would be a useful shorthand, in any case (Provided that they yield a useful model, which they seem to.).
