Not really approaching the topic of religion in any way (as far as I recall), but Bill Bryson - “A Short History of Nearly Everything” is a neat book, especially if your knowledge about the world is grounded in religious teachings.

Basically it goes through a lot of the scientific knowledge we have today and tells the story of how it was discovered, focusing on giving answers to “how we know what you know”. It’s a bit oversimplified in many areas, but it’s still pretty educational, entertaining, and at times pretty funny. The part about Henry Cavendish (18th century chemist) is hilarious.
