One thing that really draws me back to Christianity is that if everyone were to live according to basic Christian principles then the world would be a better place. People would treat strangers with kindness, would regard their wives and husbands with affection, would raise their children to be good citizens, and would be honest in their dealings with others. So it's like, even if it's all bullshit in terms of the supernatural aspects, it offers a good moral code to live by.
But I'm not totally certain that the supernatural aspects are bullshit. I certainly suspect they might be, but it does make sense to me that there could be a creator God and that that God would want some kind of relationship with his creatures.
