The sun'heat cycle is the ONLY consistent
cyclical energy cycle that lasts long enough for anything
to adapt to it. It is so inherent in all life and how
life reacts to the sun/heat, night/cold and summer/winter cycles that perhaps
we miss the
500 pound gorilla that stares us in the face.
Life of course is a blatant and obvious adaptation
to the heat cycle - what other power source could it adapt to?

I think you are missing my point. Life does not emerge.
chemicals do not emergy out of nothing. What survives the heat cycle does so at
a similar temp.
If chemicals A survive and activated at 70 C on Sunday, and chemicals B
survive and activated at 70 C on Monday, then tuesday you have chemicals A and
B both at the same place at the same time and activated. Soon you have a
pre-symbiosis effect or a temperature symbiosis where all things surviving at
70-80C together at the same time.
We must get the order correct - we must determine the order of events.
FIRST comes surviving the sun. Then later life (which is just an evolved form
of surviving the sun) came about.
Worry first about chemicals surviving - then when they're safe - worry about
the ones that are replicating.
First things first - horse before the cart.

I don't think so. Chemical reactions at the same temperature do not vary. There
is little chance in
outcome. They are reasonably predictable.
Put a match to straw and there are not many outcomes other than fire that are
open to you.

Yes exactly. And every step of the way the sun has the final word on what
survives. I think once the new sun starts to cool, then and only then was
prebiotic life forced to find a energy substitute - that substitute was
chemical energy - which we have now.

why challenge the odds with fluke events to describe
the origin. If so I suppose magic wands could have done it to - right?
I can't rule out anything in this less than exact scenario for the origin - but
I can depend on the most likely as being that that was most likely to have
happened.

 But
>how simple can be a replicator?

Would you consider replicator in a new sense?
What if it hadn't anything to do with replicating -
but instead just had to do with surviving temperature cycle.
Ex. - in the PCR reaction - doublestranded DNA is heated up, the strand
separate, and mixed with bases.
Then its cooled - annealing begins and two excat copies are there instead of
one.
Now did life do this because it wanted to replicate?
OR did the heat cycle do this and the chemicals followed the heating cooling
process?

Cells - when they get too large they can no longer take in enough energy to
survive. IF that cell can dump half of itself as WASTE OUT - it can live again.
Is that cell replicating?
Is that cell dumping waste to survive
