Mormons believe: God was once a being much like humans, who worked his way to a higher plane. God then took a wife and gave birth to satan, Jesus, and humanity. Thus, satan and Jesus are brothers, and we are also the siblings of both.  They do not believe in hell. Instead, they think that you inherit your own planet if you do enough good works. If you are genocidal-rotten, they still believe you get an afterlife so amazing that it makes life here seem like hell. Jesus is not at all seen as the Son of God, any more than every human being, or satan.  All this from a guy looking into a magical hat.
