Gen 1:20 And God said, Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament of heaven.
The word for life is nephesh.
Gen 1:21 And God created great whales, and every living creature that moveth, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good.
Creature from the waters is nephesh. From now on I am just going to bold the word that comes from nephesh.
Gen 1:24 And God said, Let the earth bring forth the living creature after his kind, cattle, and creeping thing, and beast of the earth after his kind: and it was so.
Gen 1:30 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.
Gen 2:19 And out of the ground the LORD God formed every beast of the field, and every fowl of the air; and brought them unto Adam to see what he would call them: and whatsoever Adam called every living creature, that was the name thereof.
Gen 9:4 But flesh with the life thereof, which is the blood thereof, shall ye not eat.
Here we find that the soul is the blood.

Gen 9:10 And with every living creature that is with you, of the fowl, of the cattle, and of every beast of the earth with you; from all that go out of the ark, to every beast of the earth.
A soul (a nephesh) is simply any living thing that breathes oxygen for a living. Man is not an immortal soul, but rather an earthly creature which can die and become the dust of the ground again. What God promises us is eternal life. The Devil lies and says you already have eternal life...
Gen 3:4 And the serpent said unto the woman, Ye shall not surely die:
What God says is that we can die and become dust again...
Gen 3:19 In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.
Now, what does God say about Adam and Eve and eternal life?
Gen 3:22 And the LORD God said, Behold, the man is become as one of us, to know good and evil: and now, lest he put forth his hand, and take also of the tree of life, and eat, and live for ever:
Gen 3:23 Therefore the LORD God sent him forth from the garden of Eden, to till the ground from whence he was taken.
Gen 3:24 So he drove out the man; and he placed at the east of the garden of Eden Cherubims, and a flaming sword which turned every way, to keep the way of the tree of life.
God plainly says here they do not have an immortal soul, eternal life, and He put a cherubim to guard the tree of life so they could not eat of it.
