I didn’t say it’s the only theory of quantum gravity. You can get a theory of quantum gravity by taking standard QFT — it just won’t work at extremely high energies. Other options like loop quantum gravity do not reproduce the rest of our models about everything else. I said it’s the only theory of gravity and everything else at all energy levels, and that’s true. In fact, you’ll notice I did not even use the term “quantum gravity” to avoid the exact confusion you fell into anyway.
