I think Tom probably meant how could it sensibly be otherwise.

Nope. It simply is not possible for spacetime to be "real" -- no mathematical abstraction can possibly be "real" (for any reasonable meaning of the word).

Modeling the world as a spacetime manifold (in the context of GR) has proven to be an excellent model that enables the full theory to reproduce an enormous number of mesurements to high accuracy.
