The Lord God of Heaven created the material realm, including the bodies of human beings. The material creation was "very good" when it was made (Genesis 1:31) and it still is very good. The weakness of Eden did not come from the material creation itself. The problem had to do with the fact there was not found in man a spirit capable of governing the paradise which the Lord God had placed upon the earth.
One of the main purposes of God in Christ is to develop ruling spirits who will be able to bring order and eternal life into the material creation. The Kingdom of God is the governing of the material creation by righteous and holy spirits who are perfectly obedient to the Father in Heaven.
