Before I deal with anything else you stated, I'd like to recognize that I said mankind is born innocent. Innocence is neither good nor bad. Can you recognize that I stated that previously?
Adam and Eve were created. Adam and Eve were unique from us. We (man as he is currently) are born after their image. You nor I were ever created in the same manner that Adam and Eve were created. It is important to recognize this fact.
God literally breathed into Adam and Eve's physical bodies the very "breath of life". God didn't do this for us. We are born. It is requirement for us to be "born again" to experience a fully Spiritual condition.
Ezekiel deals with "Dead Bones".
Eze 37:4 Again he said unto me, Prophesy upon these bones, and say unto them, O ye dry bones, hear the word of the LORD.
Eze 37:5 Thus saith the Lord GOD unto these bones; Behold, I will cause breath to enter into you, and ye shall live:
The Spirit of God comes to us in WORDS. The words of Jesus are spirit and they are life.
John 6:63 It is the spirit that quickeneth; the flesh profiteth nothing: the words that I speak unto you, they are spirit, and they are life.
Such words impart knowledge to our Innocence.
Flesh certainly isn't Spiritual. It is animated in the life of the seed of the man and the seed of the women. Those two join to form life in their offspring. This is where doctrines such as Total Depravity are wrong. We are neither good nor bad when we are born. However, we are exposed to good and bad as soon as conception takes place in the joining of seeds. Some of those seeds are even genetically tainted with weakness associated with diseases. Diseases that rob the offspring of Adam and Eve of their full capabilities. (Physical genetic abnormalities.)
Our Innocence is lost in what we learn and ultimately practice. Jesus insisted that little children are precious in their Innocence.
Mat 19:13 Then were there brought unto him little children, that he should put his hands on them, and pray: and the disciples rebuked them.
Mat 19:14 But Jesus said, Suffer little children, and forbid them not, to come unto me: for of such is the kingdom of heaven.
Mat 19:15 And he laid his hands on them, and departed thence.
There is also a Spiritual battle for the minds of men throughout their lives between Satan, the faithful and God/Jesus Christ. Jesus defeated death hell and the grave for us.
Do you agree? No one has to accept the teachings of Total Depravity. I will say that many Protestants do believe in Total Depravity. Currently, most Catholics do not.
