where do you get your belief system?

I mostly just get it from my parents i am one of those kids that grew up hereing and beleiving ing what i heard and what was around me, but i am also a kid that likes to think for myself so about 5th grade or so i wipped my brain clean of everything and believe whatever i wanted, i still believe in god but its just some stuff about the bible is questionable and you just say i have to see it to believe it. I am a leader, loner, and believer that will one day be saved.
