I agree with you that life was a response to the energy from the sun.
It wasn't "Pop and Adapt" like most scenarios suggest - where life
pops up
from a random fluke event, and then over time it adapts (though how it
survives
over this time is never discussed).
But there were other energy sources - though none as powerful:
Radiation,
thermal vents, lightning, etc. What I think we both agree on is
substantial.
And that is that life is a reaction to a sun cycle. It activates when
the sun
is out, and deactivates when it isn't.
The sun cycle was the perfect energy source. It was both varied ( day
and night)
but constant in keeping the temperature in the range of liquid water
etc.
I also thank you for the url's. Sleep has a lot to tell us as does the
Circadian rhythms.
I found them interesting reading.
