Cherubim
If we were to suppose that there is a being that is right with God, that is close to the stability of the Garden, we are to suppose the beingness of Cherubim. In our Cosmology third heaven is the criteria for Cherubim. However there are higher Cherubim. The Cherubim of heaven is in 6th Heaven based on our Cosmology.
Anunnaki,The Angelic Pantheon would be considered Cherubim. That is they subsist within the Garden of Eden, while man exists outside of it. They are of space, and of the deep realities of nature.
A new born child can be considered Cherub, because they are closer to the Spirit world than adults who walk away from such a womb. A person who seeks God can obtain the beingness of Cherubim if they are under the right mindset, for to be near Cherubim is to be near the presence of God.
A cherubim outside the Garden of Eden, is simply a Fallen Angel.
