You're a pretty smart kid. Continue to question and seek knowledge and pretty soon you'll realize you don't need any of that superstition after all.
Well I am a Roman Catholic and I'm not going to get on at you because I understand you in a lot of ways. First your wrong to say your age has nothing to do with it because it does in a way, I am 17 and when I was about your age I questioned my Religion too I started to think that all God didn't exist that for some reason Jesus and God all seemed like a fairy tale to me, but deep down I didn't want to believe there was no heaven because I have lost Loved ones and the thought of never seeing them again can be unbearable. So I decided to question my beliefs and I thought I was going to be an atheist like you do because I was thinking similar things to you, I had never liked going to Church it was boring It was as though from been new born I always thought Church was a waste of time and I just thought that was it for me, My Parents are strict Catholics so I never told them how I felt about my religion I kept it hidden.
Now before I conclude my story let me tell you something either believe in the Catholic faith or don't believe at all because becoming a Muslim or Jew is silly, If your going to put your faith into something put it into something you and your family are used to because trust me if you become a Muslim it won't last because deep down in your heart you won't truly believe and then within a year you will probably be Buddhist or Jewish and that way you will never believe truly in anything and that would make everything pointless. Now I have my faith in God again because I got to 16 and I started to look at the world differently, When I went through my period of disbelieving I was thinking how much anger and hate was in the world but now I see the good in people and life itself. I'm not 100% sure God exists but then who can be 100% that he does or does not exist and I thought well you gotta believe in something, and I never really ever in my heart stopped believing not truly.
Now I can't tell you what to do because we are all different but I can see by the way you asked your question that you may never believe even if you try to become a Muslim I doubt you will truly believe because your just picking a religion for picking a religions sake, You may as well have a lottery and see which number comes out the way your picking a religion. When the chips are down and you have a serious problem in your life then look inward and then you will know. But God even if you become an atheist won't damn you to hell it doesn't work that way, its the things we do in life if we are kind or nasty good or evil that is what determines what happens to us in the next life.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
