That's because you don't know God. I do. I have a spirit inside of me. That spirit is a literal child of my Father and Mother in Heaven. He is my God the Father. All people of the fold of Adam are the same, children of my Father Father in Heaven in Heaven. That's why in our Church, we call one another brothers and sisters because we are literally spirit brothers and sisters. This also includes Jesus Christ who was Jehovah of the Old Testament. We often call Jesus our Elder Brother. But, he is now also our Lord God because he redeemed us through His atonement. Sometimes Jesus is referred to as "father." But, that is because he redeemed us or adopted us as His own through the atonement. So, we have two Fathers. Our Father is the Most High God.
Now, where did our intelligence come from? That comes from being born in spirit form first. Our intelligence was placed into our spirit bodies. So, we have always existed for our intelligence has always existed. Intelligence is energy and energy cannot be created nor destroyed. Somewhere along the line, the greatest of all energies or intelligences was able to gather other types of energy and form matter. From their, a universe in which that intelligence became God and developed humanoids to enter into one of them, develop die and resurrect Himself along with a woman who was His wife. And, from that point on, he started the evolution of universes. Each one has a God the Father, Son and Holy Ghost. They are soul authority within their respective universes of which their are probably quadrillions. Or, perhaps we are only the second or third generation from the First. Don't know. Doesn't matter. We are here and have our test of life to go through.
