All religions have it's own myths, own stories, own set of values. And these are/were good stories, I mean, even though they are not true, they are certainly interesting. You won't feel bored by it.
Harry Potter has the same effect on people, like, why should I take Harry Potter seriously, why do I care what happens after Dumbledore dances with Snape (won't give actual spoilers :')
I mean, it doesn't make sense to me. Why do I care so much about a soap opera that I am watching. Harry Potter is the product of just one brilliant woman's imagination. It has no real value on my life. I have no real motivation to read that other than the fact that I like it and I want to know. Harry Potter is somewhat irrelevant to my life, than why does it or any other good story capture our imagination?
Why do I care what the next season of House M.D. entails? Why? What should I care if he dies or lives? Why :')?
