I don't believe that anything comes from Nothing. I believe that the elements, energy and intelligence are eternal by nature. I believe that the intelligence of man and other animals, plants, and even the elements are eternal by nature. There is intelligence that is associated with all matter in the universe. Thus when Moses commanded the Red Sea to part, it was nothing more than obedient intelligence. The intelligence associated with nature obey the laws of Chemistry and Physics unless God commands them to do otherwise. These intelligences give their obedience to God who cares for them and organizes them. So if you have the authority of God, you can say to a mountain, "Move", and it will move or say to water, "Be ye therefore wine" and it will obey. No longer does it go by the standard law of Chemistry or Physics but will obey the will of God.
Doctrine and Covenants 88:6-13
6 He that ascended up on high, as also he descended below all things, in that he comprehended all things, that he might be in all and through all things, the light of truth;
7 Which truth shineth. This is the light of Christ. As also he is in the sun, and the light of the sun, and the power thereof by which it was made.
8 As also he is in the moon, and is the light of the moon, and the power thereof by which it was made;
9 As also the light of the stars, and the power thereof by which they were made;
10 And the earth also, and the power thereof, even the earth upon which you stand.
11 And the light which shineth, which giveth you light, is through him who enlighteneth your eyes, which is the same light that quickeneth your understandings;
12 Which light proceedeth forth from the presence of God to fill the immensity of space—
13 The light which is in all things, which giveth life to all things, which is the law by which all things are governed, even the power of God who sitteth upon his throne, who is in the bosom of eternity, who is in the midst of all things.
I presume that in the eternity past, a God, as a self-existing intelligence, was able to command the elements to form a spirit body and later a physcal body for himself. He was able to give laws to the intelligences that combine with the varying elements for them to obey. He also has learned to organize intelligence and matter into universes and all matter and life that exist. There are varying degrees of intelligence in the universes.
Abraham 3:18-19
18 Howbeit that he made the greater star; as, also, if there be two spirits, and one shall be more intelligent than the other, yet these two spirits, notwithstanding one is more intelligent than the other, have no beginning; they existed before, they shall have no end, they shall exist after, for they are gnolaum, or eternal.
19 And the Lord said unto me: These two facts do exist, that there are two spirits, one being more intelligent than the other; there shall be another more intelligent than they; I am the Lord thy God, I am more intelligent than they all.
Mankind starts out as a self-existing intelligence. He then becomes personage of spirit with spirit matter that makes up his spirit body.
Doctrine and Covenants 131:7
7 There is no such thing as immaterial matter. All
spirit is matter, but it is more fine or pure, and can only be discerned by
purer eyes;
God has made creation a part of eternal existence. Procreation of life is a part of existence.
Mankind then takes on a physical body in a mortal sphere and eventually is resurrected to live out eternity combined with the elements of his body.
Doctrine and Covenants 93:33
33 For man is
spirit. The elements are
eternal, and
spirit and element, inseparably connected, receive a fulness of joy;
