According to LDS doctrine, we started out in Heaven, living as the spirit sons and daughters of God, in His presence. Our love, admiration and respect for Him was boundless and we wanted to be like Him. Since He, too, wanted this for us, but knew that we could only attain this state of perfection by first experiencing mortality and learning to distinguish between good and evil, He proposed a plan by which we could come to earth to gain physical bodies and be tried and tested. We were informed that in order for us to be able to return to Him, one of two things must happen -- we must either live perfect lives (something we all recognized would be impossible) or someone for whom this was possible must be willing to accept the responsibility to pay the price for our sins. The Father's Only Begotten Son, Jesus Christ, accepted this role and we chose to come to Earth. One third of God's spirit children rejected the plan and instead chose to follow Lucifer, who had also offered to be our Savior but who had insisted that the resulting glory be his instead of his Father's. He and his followers were cast out of Heaven, while the rest of us awaited our chance to be born to mortal parents and start on our journey to become like our Father in Heaven. I know... it's a pretty different view from that of most other Christians.
