Just because you can't comprehend something, Chris, doesn't mean it is incomprehensible. It's perfectly comprehensible for 96% of the population. I see no reason why 1-4% of the population should hold everyone else hostage. Religion is as widespread in humanity as language is. It's probably genetic too ya know.
When an individual can't understand language, we do not say language is an unnecessary, stupid human construct. We say that that individual has a malfunction of sort. So it is with the spiritual. Why are you unable to understand that life and people have worth and a purpose? Everyone else gets it. It's obvious, mate.
