Consciousness is a pure scientific question. We are biological units. Consciousness is a function of our biology. Questions about biology are scientific questions.
Will a biological answer be satisfactory? Is consciousness just chemistry or physics?
What a scientific study of consciousness lacks is a shared subject matter. Two geologists can go to The Grand Canyon and study the strata apart or together. Two mathematicians can examine and critique each other’s conjectures and solutions. Two astronomers can sync up two different telescopes and study the same celestial object or phenomenon.
You can’t do that with consciousness because a consciousness is an observable phenomenon to one and only one observer.
