Science is the study and proof of what the universe around us and the world around us does in a given set of circumstances. Philosophy and theology look to find how we fit in, how we want to fit in and what pattern of thought and means of existing are best.
Science can say nothing of ethics, morality or faith, yet morality,ethics and faith have much to say about not only science but everything you see and experience. The truth is that philosophy and faith have powered and motivated humanity far more than science. Faith is far more than just a religion or the doctrine thereof, it is an acceptance or a trust in something, anything that cannot be proved or predicted. Faith in a football team even though their results cannot be predicted.
Science cannot prove anything empirical about matters of faith because by definition they defy empirical scientific analysis, but to dismiss them as most scientists do is a huge error. They influence the world so much they cannot be ignored. Philosophy and theology can study these by processes of thought and belief, it is no coincidence that science began as natural philosophy, a philosophy of nature.
Also find a religion that would collapse with the disproof of the immortal soul. (Even though it can't be disproved.) Every faith has said something and had it disproved and survived, that is the nature of faith. Every major religion's original texts were based on the right way to live and exist, the concept of the immortal soul is often added later historically as an inducement, a reward for following the doctrine. But originally following the faith was its own reward, or you were threatened with mortal death, the bible only mentions Satan and Hell twice, the idea of heaven and hell was focused on in the middle ages by churches trying to get more strict followers and even money to spend less time in purgatory.
