Why is there something rather than nothing?

The question, Why is there something rather than nothing?, has long haunted me, as it has haunted many if not most people. Could the answer be quite simply that the eternal truths of logic, whose nonexistence is impossible, require "something" to exist for them to be about, and "something's" existence as inexorably requires that it inter-react and reform itself, even becoming, over the course of millions and billions of years, creatures capable of being haunted by such questions?
    I'm reminded of my favorite short poem, by Howard Nemerov:

The world's just mad enough to have been made
By the being whose beings into being prayed.

Whether it's relevant or not, it nevertheless evokes a similar feeling in me. Awe at the weirdness of things. The mystery of being.
    Could the story by which to exult, to dance, be written as paeans to the mystery, like some weird novel by Flann O'Brien—say, The Third Policeman, which was written between 1939 and 1940 and published posthumously. In the book's frontispiece, O'Brien "quotes" his fictional philosopher De Selby:

Human existence being an hallucination containing in itself the secondary hallucinations of day and night (the latter an insanitary condition of the atmosphere due to accretions of black air) it ill becomes any man of sense to be concerned at the illusory approach of the supreme hallucination known as death.

As a teenage philosopher, I found The Gospel of John more appealing than the other Gospels. The very first verse of John suggests that existence derived from those eternal logical truths: "In the beginning was the Word...." As Wikipedia says, "The Gospel of John identifies the Logos, through which all things are made, as divine (theos), and further identifies Jesus as the incarnation of the Logos." While most of the Jesus myth simply borrows from the various pagan and other religious mythologies of the period [something I didn't realize as a teenager], logos is borrowed from Greek philosophy. Heraclitus (ca. 535–475 BC) used the term for the principle of order and knowledge in the universe.
