I am troubled by the title of this story. Science deals with the observation and measurement of material phenomena. If the soul is not material then it lies outside the purview of science and in the realm of psychology or religion.
The closest science can come to a conclusion of a religious nature is that the cause of a measurable effect can not be determined and proved.
This is as it should be. Religion is founded on faith, the capacity to believe, even to know and experience, that which can not be seen and touched. It is rightfully said that God is love and it is forever true that love can not be measured.
But it is not based on blind faith, despite assertions by atheists, but on a degrees of evidential warrant.
