Well, ever since I was younger (Around the 6 or 7), I have never really believed in God. At all, actually. I used to think that there was something wrong with me, since every many people I know are strong believers in God.
Now that I think about it, I never really did ever believe in God, it seemed too unreal. And now, I know that I do not at all believe that there even is a God. I am Atheist.
And I am pretty much OK with that. Because I know that no God could possibly create all this pain.
However, a few people I knew wanted to convert me to Christianity. I am happy with being Atheist, though.
