Both writers make use of that device. In the first creation account, god says "let us make man in our image." There is no similar use in the second creation account, but in the story of the fall (which is written in the style of the writer of the second creation account) god laments that "man has become like one of us." No reference is made to any other specific being, and so it could refer to a pantheon of gods, but could also refer to spirit beings such as angels. The creation accounts do not mention angels, but at the end of chapter three we are told that god places a cherubim at the entrance of the path to the tree of life. That is the first specific reference to any other spiritual being in the Bible, since the serpent is not identified as anything but a serpent.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
