Hi John (K),
For whatever it's worth, in the purely philosophical realm, which I
consider this to be:
As Carl Sagan said, "we are all made of star
stuff." The point is that what we call a system, in order to identify some part of this grand whole, is by definition an abstraction (whether the "we" is we-humans/scientists or we-life or rabbits, etc.), and the only completely whole system we can point to is the system of everything. This also relates to the ideas discussed last summer about why there may be no truely closed systems, i.e., closed in all respects. There is no major disagreement. Sort of a cosmic "six degrees of separation".
It's the same notion that the water molecules that are flowing
through our veins today have been in countless other creatures through time
including dinosaurs and so forth. Ick!
