The curious Incident of the dog in the night time2

An interesting quote I found in the book was when Christopher says on pg 33, "i think people believe in heaven because they don't like the idea of dying because they want to carry on living and they don't like the idea that other people will move into their house and put their things into the rubbish" I never thought about this before, the idea of why people actually believe in heaven or hell or an afterlife until I heard that from him. He has a very strait forward way of thinking, he talks about the stars in the sky, prime numbers, how much he likes math, and facts. Because heaven is not a fact or something proven, I almost feel like he cannot comprehend to even believe in it.
