As I understand the word ALONE, psicologically also can be understood as in needing of something or someone.
I don't fell that God is incomplete. As I understand God don't need anything. For me God can't be alone a we humans can be alone.
I also remember a book in which the WTBT taught about God as the creator of space time. Aristoteles defined God as a motor without movement. I understand God like that. He don't need movement to produce energy. He don't need space or time.
Regarding electrons, as you know we can't see electrons because the wave of light is bigger than electrons. So in some way God can have some other kind of eyes to see beyond light, and He also can manipulate matter in under microscopic scale. Is my weird idea that the spiritual beings live in a "space time" under electrons, that's one of the reasons because we can't see them, but they had the power to influence our world.
I understand creation as an act of love. And for me the word creation applied to God works means to obtain something from nothing, also without experience.
As and example: I understand the God don't need experience for knowledge. He knows good and evil without experience the evil. As I understand Satan is the creator of evil. But God knows evil previous to this Satan creation. I don't believe in Trinity and as I understand His Son is only begotten, so it had a start and as I was taught as child: the "Holy Spirit" is a by product of the love between the Father and the Son, so "He" only had a beginning.
... this are only my weirds personals opinions.
