For traditional Christians: God is outside of creation - and every-thing else is inside it (including, you, me, and every entity)
For some Eastern Religions (and their Western oneness/ perennialist derivations): nothing is outside creation (because it is one) - including that 'deity' is inside of creation (hence is not fully a creator).
For me: God (as creator) is outside of creation - and so is somewhat of all Beings (including you and me). Beings are such that each has somewhat outside of creation (which is divine, original, generative) and somewhat inside.
That of us which is inside creation is inside God's creation; and that of us which is outside creation can contribute to God's creation.
