As man is, god once was...
Once upon a time there was a man that lived
on near a planet called “Kolob”, not so very far away. It came to pass that this man lived a good life and became a god; he came to another little planet called “earth” with his wife that he had married on his home planet.. In their exalted states, this god and his wife gave birth to “spirit children”; the first-born was Jesus – later would come Lucifer, along with many other "spirit children".
The “father-god” was concerned about the future salvation of humans on this new planet and he had a planned. One of his sons (Jesus) agreed with the plan. The other son (Lucifer) did not agree and rebelled, convincing a large number of (pre-human) spirit-children in heaven to side with him. As punishment, the father-god cast Lucifer out of heaven and made Lucifer’s followers into demons, who could never, ever be born as humans(1). Another large number (although not the remaining) of spirit-children sided with Jesus and would be blest to be born as Caucasians. The remaining spirit-children (who had not taken sides) would be born in the line of Cain, as non-Caucasians (black people).
