You don't have to believe in God to attend meetings.... You don't even have to be spiritual though most us get to a point where we in the spiritual. To many crazy things happen to help us when we can not help ourselves......
The program is about a Higher Power as you understand it...... That could be God in the traditional sense or it could be you talking to the squirrel in your back yard when you are having a bad day....
Or it could just be recognizing a really strange coincidence that you have no way of explaining in any other manor than that had to be a higher power.
Do not not go to a meeting because you are afraid it might be religious in nature becasue the only person you will be hurting will be you....
