For animals to eat before the fall involved the death of plant life and seeds in the digestive tracts of animals (Gen. 1:29). This is part of the natural process God designed as "very good". Marine life fed on other marine life organisms on down the food chain. A perfect Adam and Eve were sloughing off dead skin cells, growing nails and hair, passing digested waste, etc. All this involved decay of some kind as a natural biological process that God designed as perfect.
The "corruption" that would arise as an effect of sin was first of all spiritual death of the soul and separation from God, causing eventual death of the body entirely.
I did. Can't you see the TWO promises God made in Genesis 8:21? First of all, He said He would not again curse the ground (as in Genesis 3:17). Second, He said NEITHER would He again smite every living thing as He had done with the flood. That's TWO different things He promised - not just one.
You did not answer my questions. That is because you can't. You are avoiding the obvious.
There are three absolutes in the description of the fall in Genesis 3.
Firstly, the Fall of man caused the fall of creation.
Secondly, there is no mention or description in Genesis 1-3 (or anywhere else in the Bible) that there was any vestige of the bondage of corruption in creation before Adam’s fall.
There was nothing bad or corrupt in the created world at the beginning. There was no death, no decay, no suffering or pain to be found anywhere in God's perfect world. Man, and the animals, fed off the plant-life, something that in God’s eyes was not considered death. Genesis 1:29-31 confirms:
“And God said, Behold, I have given you every herb bearing seed, which is upon the face of all the earth, and every tree, in the which is the fruit of a tree yielding seed; to you it shall be for meat. And to every beast of the earth, and to every fowl of the air, and to every thing that creepeth upon the earth, wherein there is life, I have given every green herb for meat: and it was so. And God saw every thing that he had made, and, behold, it was very good. And the evening and the morning were the sixth day.
Eating animal meat was not sanctioned until after the flood. Genesis 9:1-4 says:
“And God blessed Noah and his sons, and said unto them, Be fruitful, and multiply, and replenish the earth. And the fear of you and the dread of you shall be upon every beast of the earth, and upon every fowl of the air, upon all that moveth upon the earth, and upon all the fishes of the sea; into your hand are they delivered. Every moving thing that liveth shall be meat for you; even as the green herb have I given you all things. But flesh with the life thereof, which is the blood thereof, shall ye not eat.”
After the flood, it seems like God lifted the restriction on eating animal meat, and gave “Every moving thing that liveth shall be meat for you; even as the green herb have I given you all things.” This is pretty clear.
Significantly, when creation is returned to the Edenic condition, being banished of every vestige of the curse, the herbs will again be the only source of nourishment. This is not construed by God as death. Revelation 22:2 says: “In the midst of the street of it, and on either side of the river, was there the tree of life, which bare twelve manner of fruits, and yielded her fruit every month: and the leaves of the tree were for the healing of the nations.”
Thirdly,
the announcement of the curse upon the ground was simply God’s ordained time to reveal this truth to fallen man. The fact there may have been a brief interval between the inception of this curse and the revelation of the same to man does not negate this truth.
Satan enjoyed no authority or dominion over creation at the beginning; therefore, he had no ability or power within himself to directly bring corruption upon the earth. Rather, Scripture carefully links the condition of the earth to the state and obedience of man.
The privilege of ruling over creation belonged to man alone. The devil knew that man held that privileged position in the form of Adam. We see this in Genesis 1:26-28:
“And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth. So God created man in his own image, in the image of God created he him; male and female created he them. And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth.”
From a positional perspective, man was installed as ruler of this world at the beginning. God delegated incredible authority to him over the animal life and “over all the earth.” The rule over the created was his has be allocation. To gain any influence over creation, the devil knew he had to attack the holder of that authority – Adam – and cause him to relinquish his favoured position. When the devil decided to attack, he came at him indirectly through his wife Eve.
Through sin and disobedience, Adam gave away his dominion over all creation. Adam’s transgression saw the introduction of corruption to the earth. Any authority Satan appropriated therefore came through man’s own failure and his abdication of his inheritance and responsibility. In short, if man had not fallen, creation would not have fallen.
