There is a great deal known about the chemistry of life.
None of what is known is special to life. It turns out to be
just the chemistry of CHNOPS and a few other players.
So we know enough about life and the chemistry of life to
know it from an extensively informed perspective. If you
know of some particular aspect of life that requires chemistry
that is "unnatural" or otherwise an exception to the innate
reactivities of our friends in the periodic table, please
do step forward and perhaps we can share the Nobel Prize.

It's an observation really. It's as much as observation
as saying that a rock doesn't require magic to keep
it being a rock and spontaneously sprouting wings and
flying away.

But that does not prevent others from doing so. Your argument
is that there is a specific problem in the certain complex
arrangements of chemistry from occurring without the willful
conscious intervention of a "designer". There are many reactions
willful conscious and intelligent designers can't get to occur.
As far as we know so far, the ones they can get to occur are
the same as the ones that can occur spontaneously because
designers do no change the laws of chemistry, or as you put
it, the innate potential of atoms and molecules.

Perhaps you misunderstand. I am not saying we have proven
that life arose without any outside intervention. Even if
I could provide a complete and detailed pathway I could
not prove that no intervention occurred. But we have
investigated potential pathways and have not discovered
any overwhelming barriers. That life could have arisen
spontaneously is a distinct possibility which I would add
have become a more likely possibility over the last 40
years as many reaction systems that make sense as part
of a pathway toward life have been discovered. Further,
nothing about the functioning of cellular life looks in
any way to be an exception to how chemicals react on
their own outside of cells.

Yes. It is.

I disagree.
The material exists. I don't yet know all that it is capable of.
I don't know if these designers even exist. Neither do I know
what they would be capable of.
I do know that the material that exists is capable of most of
what is required for spontaneous generation.
I know absolutely nothing about any agents that could agents
that could move the process along.
The sorts of agents I know of in today's world, could enhance
the probability of certain combinations in a rather profound
way but getting such agents to exist on Earth 3.5 billion
years ago presents as big or bigger a problem.

Spontaneous generation, aka abiogenesis, is only better
than the alternatives, not necessarily "good" science. There
are too many unknowns left to call it "good". As for what
needs to be filled in, it isn't that different from what has
already been elucidated. In contrast, finding some sort
of magical beings that can usurp the natural behavior of
matter or were darting about the solar system synthesizing
life requires something very unlike anything we have ever
discovered.

Perhaps you missed the part about "reverse engineered".
Craig did not "invent" life from scratch. His work is really
much closer to plagiarism. While we are close to being
able to design enzymes from scratch, especially given some
creative strategies for co-opting modes of natural selection
to refine initial designs, we're far from being able to
de novo design novel efficient pathways. There are some
interesting initiatives to do so but they can be observed
to mostly steal from existing pathways.
So the point is, de novo design of life requires an
intelligence/education far exceeding anything we can do.
While abiogenesis is more a matter of filling in some
blanks with reactions that are similar to ones we
already know exist.
One case is of ignorance of the existence of things
completely unlike anything we know of. The other is
ignorance of things that are not unlike things we
have learned and so could simply reflect that we
are just getting started, essentially reflecting more
on us than on the universe.

Find me a single chemical reaction that occurs in cells
or is required by cells that does not also occur outside
of cells. We have not found one nor have we identified
the need for any. I'm unaware of any chemist, creationist
or not, ID proponent or not, that would give any credence
to that ancient notion of vitalism.

There's still nothing about cells or organisms you have
pointed out that requires any exceptional chemistry.
Not cells or organisms that already exist. And I'm now
lost as to whether you are invoking vitalism in extant
life or objecting to getting all the various bits
that result in life together in the first place.

There's evidence that effectively "dead" cells can be
converted into living cells by transplanting mere
material through a pipette.
And there's plenty of evidence that chemistry can spontaneously
cross some of the pathway from disorganized precursors toward
cellular life. Repeating myself, crossing the rest of the
way does not require unprecedented types of chemistry.

I sortof knew you believed as much but perhaps do not
consider you an ID theorist. Perhaps I misjudge how many
share your view. Perhaps because the short term predictability
of weather systems makes the idea of everything being
moved by a living will to be intellectually unsustainable.
