Below is an amazing video by Yale scientist, Alexander Tsiaras, who is part artist, part technologist whose work explores the unseen human body, developing scientific visualization software to enable him to “paint” the human anatomy.
In his own words, “Even though I am a mathematician, I look at [fetal development] with marvel: How do these instruction sets not make mistakes as they build what is us?” and “The magic of the mechanisms inside each genetic structure saying exactly where that nerve cell should go — the complexity of these mathematical models is beyond human comprehension.”
But we, as Christians, know that answer to that marvel! We know that it is our God, Creator all who is at the center of all this complexity, all that is ‘beyond human comprehension’. Just makes me smile!! 
Contemplate on Psalm 139:13-16 as you watch this amazing video!
13 For you created my inmost being;
you knit me together in my mother’s womb.
14 I praise you because I am fearfully and wonderfully made;
your works are wonderful,
I know that full well.
15 My frame was not hidden from you
when I was made in the secret place,
when I was woven together in the depths of the earth.
16 Your eyes saw my unformed body;
all the days ordained for me were written in your book
before one of them came to be.
But even the hairs of your head are all numbered! Do not be afraid; you are worth more than many sparrows. ~Luke 12:7
