“Call it an isolated system if you have a problem with closed but either way the Earth and Sun are and will continue to both completely devolve rather than the Sun turning our Earth into a more highly ordered planet.”
You weren’t talking about “the Earth and Sun”, you were talking only about the earth. That is called “moving the goalposts”. The fact is that the earth isn’t a closed system by any definition because it continually receives an input of energy from outside the earth. Therefore you can’t apply the 2nd law of thermodynamics to the earth as if it were a closed system. It’s a bad argument, and you can’t save it by making more bad arguments, such as the one you are trying to switch to now.
If you want to talk about the earth+sun system, then you can apply the 2nd law to a high degree, however you can only use it to make conclusions about the system as a whole, not one part of the system. Thus, you cannot say “the earth will devolve”, you can only say “the earth plus sun system will devolve”, which is of course true, but it tells us nothing about the state of the earth itself.
That is not moving the goalposts since both are devolving [and you even agreed!] - weak debate point at best - I did not change the argument only shed more light on it. So please tell us how the sunlight [this is not directed work btw] is specifically causing more order on the Earth [more plant and animal life is not more order]. The Earth can not be both evolving and devolving at the same time.
