I will be the first to concede that religion can be extremely interesting (although not to me). My general rule of thumb is that virtually any topic is interesting once you really get into it, and religion is no exception. One can study it from within its own logic and set of doctrines (theology or Talmudic scholarship), from outside (anthropology) or through many other lenses (political, economic, etc.).
The same is true about special topics in the subject of religion, like God or gods or The Gods or however you want to express it. Now there’s a quick and easy way to get into the subject: The Official God FAQ (Frequently Asked Questions), which boils the subject down to the essentials without getting into needless complexities, you know, in the spirit of Einstein’s advice, “You should make a subject as simple as possible but no simpler.”
