Beyond Human Comprehension
The video I have linked to below blew my mind. Not that I didn't have an inkling of how this stuff happens. Seeing it this way, though, points me again and again to a Master Creator. The video is about 10 minutes long, but it is well worth your time.
One thing I found interesting was that when the first division of the egg takes place, the screen says, 'baby's first division', not 'embryo's first division'. Also, this scientist/mathematician says the development of the a person is beyond human comprehension. I couldn't agree more.
Enjoy the video!
