What if "curvature of space-time" actually is the force fields of massive objects, like the magnetic field of earth?

Why must space-time necessarily have to be "bent"? Is there really only one way to look at the nature of gravity between massive objects? That gravity is a "distortion of space-time"? I know that there's much experimental and observational evidence for GR, but how do we really know there is such a thing as "fabric" of space and time? What exactly is this fabric, at quantum level?

I want to get to the bottom of what gravity really is. Unfortunately, GR is taught like after you have a Bachelor's degree, in your masters.

Anyway, is it beyond a reasonable doubt, that the notion of "curvature" will never be replaced by another theory?

What if, as I speculate, force fields or acceleration fields, account for the bending of light near masses and all the other experimental data for GR? Is that completely impossible?

Thanks for any answers.
