The plan required the Creation, and that in turn required both the Fall and the Atonement. These are the three fundamental components of the plan. The creation of a paradisiacal planet came from God. Mortality and death came into the world through the Fall of Adam. Immortality and the possibility of eternal life were provided by the Atonement of Jesus Christ. The Creation, the Fall, and the Atonement were planned long before the actual work of the Creation began.
