We are all atheists when it comes to belief in the gods of the past, like zeus, mithras, thor. What is it about the abrahamic version of god that suggests that belief will persist? 

Paul then stood up in the meeting of the Areopagus and said: “People of Athens! I see that in every way you are very religious. For as I walked around and looked carefully at your objects of worship, I even found an altar with this inscription: TO AN UNKNOWN GOD. So you do not know the very thing you worship—and this is what I will set out for you... “The God who made the world and everything in it... gives everyone life and breath and everything else... God did this so that we would seek him and grapple with him and find him, though he is not far from any one of us. ‘For in him we live and move and have our being.’ As some of your own poets have said, ‘We are his offspring.’ (Acts 17: 22-28)

As a little boy I learned about King David and his God at Sunday School. At home I read about Theseus, Achilles, Ulysses and their gods. I did not reject these multiple gods. I sought to sympathetically engage my heroes' ground of being. The Greek gods often resonated with me more than David's.

Moving on to Pythagoras, Plato, Aristotle, Epicurus, and Epictetus, I recognized their exploration of the divine as similar to mine. Their gods -- occasionally God -- reflected aspects of my God and informed my understanding of a more expansive reality.

Nietzsche wrote, ""Wherever the Dionysian prevailed, the Apollonian was checked and destroyed.... wherever the first Dionysian onslaught was successfully withstood, the authority and majesty of the Delphic god Apollo exhibited itself as more rigid and menacing than ever." For me this is a recurring aspect of reality. In this context, I believe in Apollo and Dionysus. I experience their dialectic, I inhabit their relationship.

As an adolescent my favorite music was Also Sprach Zarathustra by Richard Strauss (via Stanley Kubrick). In the original, which inspired the tone poem, Nietzsche proclaimed, "God is dead." In the music I heard eternity and ultimate reality.

In his Zarathustra Nietzsche wrote, 

O man, take care! 
What does the deep midnight declare?
"I was asleep— 
From a deep dream I woke and swear:— 
The world is deep, 
Deeper than day had been aware. 
Deep is its woe— 
Joy—deeper yet than agony: 
Woe implores: Go! 
But all joy wants eternity— 
Wants deep, wants deep eternity. 

All religion is flawed, any serious believer will agree. This reality does not ipso facto negate the reality of God or deep dreams of eternity.
