I can understand this man's struggle, but I've accepted long ago that if we were suppose to know how all of this works God would have let us know and why. But as it is the is no reasons but always guesses. I'm okay with this because I don't think how we were made or how this world was made is the point.The whole world is related to each other and what I think God wants us to realize is that we are interconnected with each other. What we are suppose to gain from that is how we relate to each other. Are we in harmony?
From a personal view I felt more connected to God as a child. Like most people as I grew older I had to find "proof" of God. Surly as I breathe none will be given. Instead of belief I just accept the reality of God. Reality is harder ground to stand on then belief anyways. Belief depends too much on feelings which have always proved unreliable. To me God exist whether or not I choose to believe for that day.
