Do you believe in God? - I have been asked by a closed one.

I just talked with my younger brother early in the morning. I am here in Midwest harnessing everything to live my American dream, but my sweet little brother is in Dhaka, one of the most popular, most jammed, most corrupted city in Southeast Asia. He is only 14 years old. We both were born and grown up in a moderately conservative muslim family, where even though science and education are super emphasized and encouraged, we had to learn how to read and write Arabic(our mother tongue is Bengali), we are expected to pray to Allah five times, we are expected to fast in Ramadan the entire month. Guess what, after doing all these for 18 years of my life, I could escape to Japan and now in US. And I am an agnostic atheist now, doing nothing, and sometimes telling lies, or masking my lies to my parents, after trying hard and realizing how it is impossible to convert them or make them understandable or how I need to hide it in Bangladesh so that I don't get killed because of my blogging like some other Athist blogger in my country get chopped in a book fair.. so that's the context.

Now my younger brother asked me the question with courage, " Brother, do you believe in God? " And he knows me, and I know him too. We know what we are talking about before even having the conversation as we grew up in the same household, same culture. He apparently seems to be accepting his agnosticism at that earlier age. I became an agnostic at my age 20, he is way ahead of me. After all, my sweet brother.. lol. But he is young, and quite rebellious, and quite argumentative. Like he calls our mom a bitch behind her back with me... haha..because she makes our lives hell sometimes. Well, we love our mom a lot too. After some explanation of agnosticism, I had to warn him how he needs to not tell many people, as it can be very dangerous for survival in Bangladesh. I can joke around, say lots of things living in US, but it's not the same for my friends back there. Some got even jailed, told that they need psychiatric treatment. So, I hope you know how Islam punishes those who abandon. But anyway, I am happy and scared that my brother is as open minded as me, and hope one day he will be able to see the world like me, meet people of all religion and culture like I did and be the bestest best younger brother one can have. But I am scared that he doesn't do anything stupid to be scrutinized had or punished. Hope I can protect him. Just feeling to share. May be lots of you have similar experience if you have a diverse background like me. If you do, I would appreciate suggestions. : )
