Everywhere in the world people worship imaginary gods, dream of imaginary heaven and hell. In the words of Ghalib: Humko malum hai zannat ki haqueeqat, lekin dil ko khush rakhne ke liye khayal achha hai. Bilions believe in Zannat and hundreds blow themselves up believing that they will go to heaven. That does not mean heaven with beautiful houries and cool fountains exist. Belief and faith has nothing to do with truth.
