I fully understand that living things can significantly reverse entropy.
You understand that, do you? Well, it's wrong. Living things obey the same second law and other thermodynamic laws everything else does. Entropy increases in any spontaneous process. There are no exceptions.
Define complexity for me, and I'll show you how it can arise.
What word would you prefer me to use in describing the process of creating order from disorder?
Entropy increases in any spontaneous process. And your point is? Are you denying reverse entropy? Your existence seems to refute this absurd claim.
