Getting to his main point, why couldn't any of the clerics, priests, pastors, or holy men he consulted answer him as directly as you are?
Also, doesn't one's true value lie in a genetic code, especially if it is believed that God is the author of that genetic code?
The story of Adam (man) wanted a physical existence where the knowledge of both good and evil could be attained. Each of us want this, it is inherent in our nature. Physical life allows us to attain this knowledge meaning we are also susceptible to disease, inherited genetic failures hemophilia and non-inherited genetic mutation (Sturge-Weber Syndrome). Then, of course, are our own choices that effect our lives. The story tells us God cautioned us (mankind) of wanting this knowledge, but once we chose it, He promised he would also remain with us through thick and thin. Whatever trouble we ran into, made for ourselves, inherited, God could bring good from it.
The Apostle Paul had such a thorn, and he begged God that it be removed from him. The answer was not to be concerned because from that very weakness God could bring greatness. Christian teaching is that our lives come with a cross. We are to pick up that cross and follow Christ (which Paul did). St. Augustine's own choices caused his thorn, but again God brought greatness from those weaknesses.
As for why any of the clerics, priests, pastors couldn't answer? There is a great irony here, because as you can see, I got the answer I gave him from clerics, priests, pastors!

When I was still in elementary school, a new, young priest dropped by one of our religion classes. The first thing he asked was who could remember the readings and the homily from the Sunday homily two days before. Of course, none of us could. He explained that those readings and homily pointed to a "homework" assignment we were to work on during the week. We shouldn't worry about succeeding in that assignment, we were to only work on it.
So...at a young age I began to actually listen to readings, homilies and figure out the homework assignment for the week. Even so, there are plenty of times I show up at church the following Sunday and test myself with the question: What were the readings last Sunday?--and I can't remember.
