You can be agnostic or athiest and still think of religion as a beautiful thing. I would advise, however, if you are agnostic or athiest with that view, you find a religion that appeals to your belief. Raja Yoga, for example, for Hindus, brings considerable inner peace. Religions also provide some sort of network for you to share your beliefs and be with like-minded people. Even if you're like me, and decide on a religion that has, literally, no services or other practitioners in your area, there are various online networking sources that you can go to.
I am, for example, completely and utterly Taoist in pretty much everything I do (I have been all of my life), but I think of Christianity as a beautiful religion, when it's not twisted for personal gain. I think of most religions like that, in fact.
