Hi ssope, and welcome to the fray.
I find your word choice a little curious:
The pristine question
quote:
pristine
adjective
- having its original purity; uncorrupted or unsullied.
- of or relating to the earliest period or state; primitive.
Can you explain why you chose this word (expand on it)?
If evolution is truly a mindless bio-chemical process, I'm confused on how it would produce an organism with a motivation to stay alive. How does a chemical reaction produce a molecule that prefers one future outcome over another (life or death). How do you motivate a mindless molecule to actively pursue life. Why would it care. How could it care
First off evolution only deals with life, not the origin of life (that falls under the science of
abiogenesis):

2. the theory that the earliest life forms on earth developed from nonliving matter
Tangle, in
Message 8, explains that the
mindless chemical reactions occur due to the functions of chemistry - the chemical reactions only occur in certain ways.
We also know that prebionic molecules exist in space and were common on the surface of the earth and in the oceans. see
Panspermic Pre-Biotic Molecules - Life's Building Blocks (Part I) and
Self-Replicating Molecules - Life's Building Blocks (Part II) for more on this.
They are old threads, and much has been learned since, but they give you an idea of the current research into this question of the origin of life on earth.
Of course, once life exists, evolution takes over, and you have a two-step process that
mindlessly "chooses" those forms by their relative ability to survive and reproduce better:
Like walking on first one foot and then the next.
The earliest, simple life forms known are single cell blue-green algae, and they would be subject to the processes of evolution, which we can define as:
The process of evolution involves changes in the composition of hereditary traits, and changes to the frequency of their distributions within breeding populations from generation to generation, in response to ecological challenges and opportunities for growth, development, survival and reproductive success in changing or different habitats.
We can also define life as any formation of molecules that undergoes evolution.
These evolutionary processes are also
mindless, and as Stile explains in
Message 6, they occur over many generations before the first "minds" evolve, and more generations before minds aware of what is happening around them, or become conscious of being part of the processes.
It's like equating a consciously chosen hike across the united states with a baby's first stumbling steps. There's a lot that happens in between.
Enjoy.
