Feedback Control Systems - Evidence of Design?

This video explains the engineering concept known as "Feedback Control Systems" in the human body - the autonomic nervous system such as digestion, sleep, respiration. Billy Jack provides a deep dive of anatomy engineered by an infinite Creator whose designs are so wonderful one could spend a lifetime and only scratch the surface.
The exquisite complexity of feedback control systems are further fingerprints of a grand designer providing powerful evidence of design.

Thank you for making me so wonderfully complex!
Your workmanship is marvelous—how well I know it.
You watched me as I was being formed in utter seclusion,
as I was woven together in the dark of the womb.
You saw me before I was born.
Every day of my life was recorded in your book.
Every moment was laid out
before a single day had passed.
How precious are your thoughts about me, O God.
They cannot be numbered!
I can’t even count them;
they outnumber the grains of sand!
- God, The Bible
Psalm 139:14
