Ignoring an Idiot or two, if we are to ask the question is spacetime real, then first we need to define is space real?....is time real?
At one time it was thought both were absolute...We now know that to be false.
IMHO the mistake some seem to make is defining real as something that you can either see, touch, smell, or observe some real physical property of.
Space separates everything.....If we had no space, everything would be packed together back in the primordial Singularity that the BB instigated from.
Similarly for time......If we had no time, everything would happen together, and again we arrive back to the BB Singularity.
Space and time and associated properties depend on one's frame of reference......There is no universal now.
That's my simple Occam's razor deductions that I believe says it all, but here is Sean Carroll, putting it in a more extended explanation....

This brings us to the question of spacetime.
The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.
— Hermann Minkowski:
Also GP-B immediately comes to mind as the experiment that took decades to complete and a fair amount of money that showed that not only is spacetime warped in the presence of mass, but that it can also swirl in the presence of a rotating body like a planet or star.
Light always travels in straight paths, but that path is often seen to be bent or curved because it is actually following geodesics in curved/warped spacetime.
This gets us to the relevant question at hand...are gravity waves/gravitational waves/gravitational radiation real.
Again, we also have strong evidence to suggest they are a real artifact of spacetime, plus also the simple Occam's razor argument, that if space and time [henceforth known as spacetime] can be warped, curved, twisted, all mathematically verified, than why not gravitational waves caused by asymmetric S/Nova explosions or similar catastrophic cosmological events?
While spacetime warpage was evidenced before GP-B, the Lense Thirring effect was far harder to detect. Likewise the same problem exists for the direct detection of gravitational radiation. So far we simply have not had the technology to directly detect them, although the evidence remains convincing.
All the above are facts and can be found in any search one would like to conduct. None of it is contrived bullshit, perpetrated to align with one's own alternative agenda governed by personal delusions of grandeur about one's self.
All the above are observations in how our Universe operates.

The easy fraudulent excuse and way out for our cranks ratbags and nuts in general.
