Is the soul a product of body functions???

First what is soul? what we know now is that soul is something that is not physic, something that is inside us. But this is more religious believes there is not scientific proof that we have a soul inside us. But in ancient times in the times of Aristototle soul was something extremely important, it was like our main organ that controled everything. Aristotle thought that our soul also was something that could survive to many things even dead. When we die our physical body left this world and didn't exist anymore, but our soul survived and revived into another body.

He also said that our soul keeps and saves information memories, experiences. And when it revives all that we do is remind. Also our soul manifestates when we are happy, mad, sad and it does that through our body. So our body is like an instrument for soul to express and manifestate differnet estates of our mood. so soul isn't a product of body functions, body functions are a product of all the manifestations of our soul
