Thinking about the calendar of my existence, what date would I pick as the best?
I remember none of this.
All the evidence I have of my birth is a piece of paper saying so, some photos before and after the fact that may be of me, and the stories of my mother and father and a few other eyewitnesses. I understand human biology and how it works, having had three children of my own, but that doesn't prove I was created the same way. With talk of clones, existing doesn't prove birth. I can only accept I was born in the normal way on faith and trust in those who told me about it.
For you created my inmost being; you knit me together in my mother's womb. I praise you because I am fearfully and wonderfully made; your works are wonderful, I know that full well. 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, your eyes saw my unformed body. All the days ordained for me were written in your book before one of them came to be. --Psalm 139: 13-16 NIV
