It’s crazy how even though we are raising our little guy non-religious he has “learned” so much from kids at school/friends. We have started playing a game with him called “Fact, Fiction, Belief” where you have to name, you guessed it a fact, fiction and belief. For example, a fact is “a tree is a plant” a fiction would be “trees can walk like ents” a belief would be “cherry blossom trees are the most beautiful plants in the world.” It has really helped him see that beliefs are kind of their own category, they are real to the person who has them but not necessarily shared by everyone.
