Only some other part of human anatomy, not some metaphysical concept like the soul. And, if you adhere to scientism - that science is the be-all and end-all of truth - science showing consciousness resides in the brain is all the proof you need. It works for some people, apparently.

You're right that it's wise to recognize the limitations of any endeavor. I do consider the scientific method to be superior in terms of establishing tentative truths for reality beyond my experience, but it is in no way unquestionably absolute and is secondary to my direct experience. Approaching "truth" claims as tentative and pragmatic helps prevent scientism also.
There is something to say about the uniqueness of the scientific method compared to other human traditions, however. It seeks to get at the truth, whether or not that truth ends up being emotionally satisfying and uplifting for humanity or not. It challenges us to question our established pre-conceptions and learn to adapt to reality regardless of whether it conforms to our cultural symbolism. Other traditions don't challenge us in the same manner and some even teach to suspend reason entirely and practice willful ignorance whenever new evidence conflicts with established beliefs.
Science does seem to strongly indicate that consciousness arises through the biology of the brain. It doesn't matter whether or not I find this to be satisfactory because it's difficult to deny whenever I actually investigate studies and experiments demonstrating it with an open mind while suspending preconceptions. It is possible that there's something ethereal, such as soul, interacting in some manner to strongly give the impression of physicalism while actually being something otherworldly, but I don't know that and cannot just pretend that I know. I can choose to believe it I suppose, but I'm more interested in trying to live life with just what I can know, or think that I may know, without making any excessive leaps in logic or asserting unfounded assumptions. Perhaps I'm just a product of my education, but it is what I genuinely think to the best of my ability and have not yet encountered any conflicting evidence from my direct experience.
