At this point in time I would likely classify myself as an atheist.
I was raised in an evangelical christian home, and was an active christian for most of my childhood. I first started to become disillusioned with my faith around the age of 11 or 12, and my faith quickly began to fade after that. I've continued to attend a christian church even to this day, mostly for the sake of my family. Both of my parents were christian missionaries, so I don't know if being so deeply steeped within the religion as I was growing up led to my eventual rejection of it or not. I suspect it mostly came down to the idea that I have a lot of trouble with the idea of faith, with few people within my religious community offering any tenable answers.
I've never really tried looking into any other religions, mostly because I suspect they wouldn't interest me much either. I do find certain aspects of religion very interesting in general, but I don't know that it is anything I would ever actively choose to believe in.
