Query: An all-encompassing religious thought piece

This book, while being an entertaining read, was also something more - a thought piece on the viability of some existence outside the conventional wisdom which exists in human religion to date. The question of which group of believers is right is presented in an insightful and thought provoking way - in the spirit of Mark Twain's Letters from the Earth. If you like to think about existential matters, and can put your beliefs to the test, this is the book for you!
