Here is my own theory on the subject.
We believe in what is called "Eternal progression"
We also believe that God is pure intelligence and truth. Intelligence is learned, and God learned it from somewhere. We came to this earth to become like our heavenly father, and we could not become like him had we not become mortal and experienced death and to "descend below all things."
I believe that in the very beginning there was a thing called evolution and that through knowledge and the eterneties, a being became the first God through experience and perfection. then because of love and righteousness, continued this throughout all time and eternity untill we get to our Heavenly Father. who then in turn created us and put us through the exact same steps he went through to get where he is at.
Just like a child grows up to become an adult, and then eventually a parent, and the process continues. This set of principles mimics what happened/happens in heaven.
God works in a naturl order of things, and Spirits are Matter, they are more refined than our primitive mortal eyes can see without the help of God.
God did have a father, and he is seated at the right hand of his eternal father in heaven, and enduring will eventually bring us to the same place, and have our own continuation of the seeds forever and ever.
