Yeah, when she gets older, you can ask her why she believes in God. You don't have to make any negative statements on the matter. If you get her questioning her own system while simultaneously not enforcing it, you're giving her the ability to evaluate her own position and make her own decisions.
For the time being, just don't enforce the belief system and lead by good example.
