Well, apparentley, according to the holman illustrated bible dictionary, often the soul is equated with the whole person. Genesis 2:7 states God proceeded to form the man out of dust from the ground and to blow into his nostrils the breath of life, and the man came to be a living soul. The first man was a soul. other scriptures support this. The bible states all living creatures-human or animal are souls. The bible also states the soul that is sinning-it itself will die (Ezikiel 18:4).'souls' (whatever they are) to which there is no evidence (just like religious beliefs)
With regards to religious beliefs it has been said the predisposition to religious belief is the most complex and powerful force in the human mind and in all probability an ineradicable part of human nature.
