The deterministic mechanism by which life somehow evolved from a life spark to single cell life to organ life to multiple organs/body life, and then finally spread to the evolution of millions of creatures has not been proven by scientific methods.
The "life spark" concept should be pursued in one of the
Origin of Life forum topics.
The "spread to the evolution of millions of creatures" concept should be pursued in one of the
Biological Evolution topics.
Biological evolution only presumes that life on Earth somehow started - The "life spark" may or may not have been the work of God.
