"You could put a healthy living frog in a blender and blend it up then take the compound and wait and wait and wait but no life will spontaneously arise from it even though it started as a living entity. Even though you began with all of the components of life you would not observe life spontaneously arising from this mixture. Why? Because life only comes from life."
