Chaotic chemical reactions produce nothing but chaotic constructs. Biology is anything but chaotic, it’s our minds that inject the chaotic notion because biology so overwhelmingly complex.
The creation of the Krebs cycle wasn’t a chaotic process. It require a very specific sequence, even if the surrounding ocean chemistry was a chaotic brew.
Also your words still don’t acknowledge the importance of the changing planetary environment and its impact on the types of life those processes could achieve.
The Ediacaran - Cambrian Explosion happened when it did, as a result of the consequences of a “Snowball Earth”, that scoured a ~billion years worth of geology into fine powder and sent it off into the seas. Thus providing the building blocks that the already well established biology of the very tiny, could then exploit to reach new heights of biological achievement.
This bring me back to appreciating the hierarchy of life.
At each stage the amount of survivable chaos is reduced by many orders of magnitude.
So sure life is, given proper conditions, must exist on other planets, and is probably inevitable. But, that’s still a few billion years (and a nearly infinite amount of ‘good luck’) away from a planet that can host a god-like creature like we are.
Planet Earth, our home… we’ve got so many questions about it! How was the Earth formed? How did animals get on Earth? Why did the Earth split into continents? When did the dinosaurs go extinct? Here’s a video that’ll show you the history of Earth in a nutshell. What if we could fit our planet’s history into 24 hours? Let’s watch the Earth evolve!
