Atheist: to be or not to be

Mandy
So I've been contemplating for a while whether or not I believe. My family in general are believers. Some go to church some don't. But my mother who raised me, never goes or went to church. So needless to say I didn't go to church. I got baptized before I joined the military though I really had no idea why it what the process really even meant. I just don't know how I feel. I do know I don't in one being creating all this. I don't believe I should worship something I can't see and be punished if I don't. Anyone care to explain why you became atheist? 
P.s. I'm not willing to study the bible and read up on why I should or shouldn't believe. Also don't come on my post telling me your God is real, this isn't what my post is for.
