Questioning is the most important part in intellectual development, as every pursuit of truth starts with questions. My questioning habit started in the age of 11, after reading His Dark Materials trilogy by Phillip Pullman. The concept it delivered, that God was not divine, blew the whole doctrines and values I'd been taught in my life.
For my whole life, I was taught to believe that God was the creator of the whole universe. People who question are considered infidels in my society. When my classmate Naswa proclaimed that she didn't believe in God, there were murmurs in my fellow classmates saying what an immoral person she was.
However, I faced the same dilemma soon after; I started questioning the whole religious and moral values I've been educated. Was God divine? Did the religious rules and rituals I've been doing even had sense at all?
After deeply thinking and researching for a while, I came to a conclusion that the phenomenons depicted in the trilogy couldn't exist in real life, thus the concept it brought, that God was not divine, might be right or wrong. Meanwhile, I found that the big bang theory combined with Newton's law of inertia are the proof of the existence and divinity of God.
In the end, I believe in God because scientific theories are more trustworthy than fantasy novels. The novel didn't alter my belief, I am still a faithful Muslim, but it taught me to question.
In fact, you never explained why questioning is so important to you. You are telling the Comittee what happened to you, what taught you to question. However, I believe, this question has two side.
1. They ask you what idea or experience was important to you (describe it)
2. How was it important - what did it change in you, how did it help you later on? (prove it really was important to your development)
