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. By changing genes scientists recently constructed things one could not possibly create by simply changing matter. The Principle states that spirit and matter are not separate, but one from the beginning. Even in the smallest particle these two aspects coexist.
