Decision making processes

The Earth should not stay empty; destiny of our planet was much more different as other planets elsewhere in Space. Thanks to meeting circumstances for life, Earth and nature develop living structures all over the globe.
All circumstances were not meet at the beginning of age Earth to launch quicker evolution as it was in reality. Certain changes should happen later to develop evolutionary processes to current state. Question is how conscious were evolutionary processes to manage emergence of life?
Transition between simple-celled life and first complex
multicellular life were about 2-3 billion years.
According to scientists, certain occasion happened as Great Oxidation Event and
particular development of cell communication.
When we thinking about meaning of evolution, it's is the rise of intelligence.
Everything in Space should reach certain stage of existence. To develop stages
and create next steps within evolution.
When we look on evolution closer, we observe one simple
fact; it is always about new decision make which perfectly works.
New specie by mutation or evolved brain and neural system during certain period
of time.
Our knowledge during our lives is about learning processes. We improve what we done, what we observe or created before. The same our nature was doing within surrounded environment and living structures. Decision making 'this is good, this is going to work, this is healthy viable organism for life.'
The evolution is deep written within law of nature. It once happened and now we searching for its secrets and explanation. We need to decode hidden system as a whole. To describe its complexity. Like organism communicate with environment, evolutionary processes observing the surrounded environment.
