Spiritualists fight for their ideological beliefs of a eternal god creator for sociological reasons such as their own self empowerment, redemption of their sins, their own eternal existence after they die etc. etc.
Scientists and their varying studies have none these psychological connections, rather they strive for objective truth to understanding how this universe came to be by studying physical evidence .
Unfortunately scientific discoveries do not connect or support all the appealing aspects of which spiritualism can offer in spite of getting closer to the truth of how, why and what.
