I was raised Christian for as far back as I can remember. I was never exposed to any alternate beliefs or view though, so I never really questioned anything I believed. Then when I was an adult and went to college I was exposed to new ideas and met people of different religions. So I wanted to find proof that my religion was the correct one. When I looked for proof, not only did I not find any for my religion, I didn't even find proof that any gods exist at all. So I stopped believing.
