Personally, I think we all have to walk our own path and find our own belief system out of our own experiences.
Once I was listening to "Science Friday" on NPR, and they were discussing belief in God. A Jewish Rabbi called in to the show to say that, in Judaism, it is not necessary to believe in God as "a Being," but as "Being itself." Think about that perspective as a starter.
If I were in your place, I would read some books and take some classes. I took college courses in Old Testament Survey, New Testament Survey, Introduction to the Study of Religion, and Psychology of Religion. There are many different perspectives on God and religion. You might want to take a class in the History of Christianity if there is one in your nearest community college or university. In any case, there are books and internet info on the history of the church or any religion. You are like the fly that has lived in the vinegar jar and thought it was the sweetest place ever because you'd never tasted honey. Get out there and taste the honey!
You are embarking on a journey of opening your mind to all sorts of possibilities. You decide.
Best wishes!
