Originally this world was a reflection of God's mind, which is the base of man's spirit mind. If man hadn't fallen, the world that is the shadow of God's mind and the world that is the shadow of our mind would have united into one. Man would have found true happiness, satisfaction and joy in such a world since it would have been a reflection of his ideal. Unfortunately, this world became a shadow of man's fallen mind, the complete opposite of God's original ideal. Things can be changed according to our attitude.
Men have a mind and a body.
All things have a mind and a body, just on a different level from man's. Man's body is made of cells and each cell is made of molecules, yet a cell or a molecule cannot be compared to a man. Many molecules together compose a physical body, which is more than just a collection of molecules. There are also genes. Each being's character differs according to its genes.
