“And all flesh died that moved upon the earth…everything on the dry land in whose nostrils was the breath of life died.”
So we see all living creatures in the air and on land are conceived of as having a bi-partite nature of ‘flesh’ and ‘breath’. There is no distinction between human beings and animals in this way of thinking. Animals would seem to partake of a soul that is not distinguished, at least in this context, from a human soul. What does distinguish human beings is being made in the image and likeness of God.
