The Building Blocks for Life on Earth:

No, read Paddo's quoted passage of Abstract, in Post #1, about the volatile materials, which until then I had not even considered at all, but his post started the mutual analysis of known evidence.
My initial point was that Theia was big enough to deliver sufficient amounts of water to create our current oceans.
AFAIK, early Earth did not have a lot of water , if any at all.

p.p.s. From Post #16

This may explain why life is very likely to develop where there are sufficient raw materials in a dynamic environment.
The secret lies in the dynamical self-assembly of biochemicals, a common occurrence everywhere.

From one to many: dynamic assembly and collective behavior of self-propelled colloidal motors

Plus Darwinian evolution.
They become "biochemicals" via Darwinian evolution. Before becoming part of an evolutionary development, they are just chemicals - no "bio" attached.

 

I'd like to continue this line of thought with this very interesting lecture by Robert Hazen on the "co-evolution of life and minerals", based on this provocative question by:

I hope this is the appropriate sub-forum.

Here Robert Hazen explains the specific co-evolutionary processes of life and rocks (minerals).


Note that Hazen incidentally touches on the subject of "Big Data", or what Tegmark calls "Hard Facts", rather than asking "Hard Questions".

But most interestingly, it seems to me that Hazen actually is describing the process of Abiogenesis, the gradual evolutionary process of forming biochemicals from pure elementary chemicals and their gradual transformation by natural selection into semi-alive anaerobic protists feeding on minerals and the appearance of the first Prokaryotic organisms and finally, with the advent of oxygen, into more complex aerobic Eukaryote organisms.

To me, this sounds eminently logical and the fossil record seems to generally support this type of evolutionary chronology.
