Somehow I think that an agent intelligent enough to create a universe and something as complex as life, would not have the human failing of creating something unintentionally.
On the other hand you mention that "Increasing chemical complexity" is not observed to happen within nature without an "intelligent agent" behind it, I assume then that you agree that any life-form should be considered an "intelligent agent", as all biology increases chemical complexity of the immediate environment around it during it's life-cycle. Would you say that's a fair assertion or am I missing something?
Not quite. I was thinking more along the lines of origins- that process up to the point of the first fully functioning, complete, living cell. There's also the fact that life is pretty fragile, and that it's more likely not to survive than it is to survive.
I'm not saying that any individual cell is the intelligent agent, but that there's an intelligent agent outside the system that accounts for that. Whether it's constant upkeep, or occasional tweaking.
The 2nd law is strong enough that deterioration sets in even before the death of the individual in that process called aging. The 2nd law couldn't be a law if it did not apply to all systems within the physical universe, therefore something in biological systems is temporarily overriding it.
That's not true of single celled organisms, nor is it true of the germ line of multi-celled organisms.
The egg cell that started your life is in effect, a single celled organism that has been continuously alive and reproducing as far back as life itself.
