Aside from the specific theory of General Relativity, it can be shown by simple
thought experiments that any theory which obeys the Equivalence Principle
(the identity of gravitational and inertial mass) and Special Relativity,
both of which have been verified to exquisite precission experimentally, must
also attribute non-Euclidean geometric properties (i.e., curvature) to space.

Part of the elegance of GR is that it identifies this necessary curvature
with gravity.
