Reddit mentions: The best children philosphy books

Late to the party here, but Our Family Tree and Life Story are both great evolution books for kids, as well as Born With a Bang: The Universe Tells Our Cosmic Story and the subsequent books in that series. Older Than the Stars and Big Bang!: The Tongue-Tickling Tale of a Speck That Became Spectacular are both good ones about big bang theory. For world religions/different beliefs, try What Do You Believe?, The Kids Book of World Religions, or maybe a collection of writings from different religions such as A Child's Book of Blessings and Prayers; a book like What Is God? or About God might also prompt some good discussion.

(if you have a UU church nearby, might be worth checking out - they can be a great resource for atheist/agnostic/multi-religion households trying to make sense of these issues!)

I didn't see how old your kids are, but for ours (9 and younger) this book and the rest of the series from the same author have been a nice replacement for night time "scripture study", which we were pretty good at (fhe was a different story....):

They are definitely geared toward younger kids, but our 9 year old enjoys them, too. We try asking what they learned at the end of each story and have a conversation about it, sometimes more successfully than others, as is the case with littles 😂.

Any religion that believes in Christ is Christian which is all of the ones you've listed.
The differences?

Catholic: One of the earliest christian religions. Split with Orthodox Christians about 1000 years ago. Catholics one pope Orthodox Multi-popes.

I'm being very vague BTW

Protestant: Didn't like pope went their own way.

Anglican: Henry the 8th didn't like pope or wife. Got rid of both.

Lutheran: Martin Luther says Nein to Pope! Does it his way.

Jehovah's Witness: Figures all the other Christians are interpreting bible wrong. Puts their own spin on it.

Mormonism: Not only wrong interpretation, they added some more to the bible. Made a Zane Gray Testament of sorts.

Baptist: Again no Pope puts their own spin on the bible. They like water.

There are some great books that give an overview of each religion.
There's a kids book called 'What I believe'. It's actually really good for people who are curious.

I'm an atheist as well but I lean towards Buddhist Philosophy. (which has no deity BTW)
It's great that you're curious. To me a true Atheist harbours no anger towards religion but a curiosity for better understanding.

Edit: Maybe this is the book I was thinking of. You may feel silly but it's a great introduction that isn't too heavy!

Hey OP, this is the book that my formerly Catholic now atheist parents read to me as a kid.

It's a pretty simple read, meant for kids, about the fact that many people envision God - and by proxy, religion in general - in many different ways. And, of course, that some people don't believe in any God, or some just aren't sure.

I think discussion is a good thing, because kids will encounter religion, all around them, from a young age. Learning early on that many people think they have the one right answer was, for me, the first step to understanding that maybe people just don't actually have the answers, and maybe all this "God" business is just something that different groups of people have made up in their own unique ways and told stories about over the centuries.

Anyways, highly recommend the book. Bonus points if you get your kid to read some of it!

Yep absolutely, as long as they are getting a broad spectrum of different viewpoints. There are several good books about comparative religion geared toward children too.

What do you Believe is a really good overview of the worlds major religions for kids and What is God is excellent at explaining that some people believe in god but leaves it up to the child to determine what they believe.

First, keep taking him to church if he wants to go. I'd give him a timeline of when you'll stop going with him though else he'll hold out hope of reconverting you and that isn't fair to him. However, start taking him to science lectures and free thinker meetings or skeptics meetings or whatever you have in your area. Talk to him about how difficult it was for you and that you understand he's confused and that's it's ok if he still believes which I know you've done but keep doing it.

The Little Book of Big Questions would probably also help as the idea of god is just one of many questions with many possible answers. It will get him thinking logically.

I haven't read anything from this series, so I can't vouch for the quality of the books. But it sounds like they're exactly what you're looking for.

Yea /u/Stutturdreki linked to r/atheistparents and I found a book that would be ideal...

My parents gave me this book when I was a child. It really helped me understand religious diversity. My grandparents also gave me a book of Bible stories for kids that had stories from the Old Testament in it, too (some of the ugly ones), and whenever I wanted to read a religious text my parents would get it for me. Basically, my parents made sure that I never wanted for knowledge.
