Let's get real for a moment about the most basic, fundamental, human beliefs-- our beliefs about  who and/or what we are,   where we came from,   why we are here on Earth,  and  what happens to us when our body dies?  We have hints, best guesses, an much evidence pointing in particular direction, but as for specific, exact provable answers, there are none.   

The most fundamental question of all time is about the unknown and unknowable mystery we call "Creator/God."   Does the Universe have a creator or is everything an accident?  If it has a source, what's the nature of that source, and what is our relationship to that source?   All of the above uncertainties are commonly lumped into one question:  "Do you believe in God?"   

We can hear countless hours of countless men and women telling countless stories and countless so-called-facts about "God" to anybody who will listen.   Rarely, if ever will you here anybody define what they mean by the word "God."  This lack of clarity creates a huge problem.   Any time anybody mentions the word "God," the listener immediately applies his or her own personal definition of God to the conversation.   Those definitions vary widely and each precipitates its own beliefs and behavior patterns.

Before we can answer the question, Do you believe in God?, or have even a remotely, coherent discussion of the topic, we need to define what we mean when we say "God."  Here are the two main, commonly accepted, completely-at-odds-with-each-other perspectives on Creator/God: 

The False Face of God:    

Are you talking about a fickle, angry, jealous, easily displeased, wrathful,  vindictive, vengeful, super-human being sitting on a throne somewhere overhead in the sky?   Are you talking about a god who  (for reasons that completely escape human understanding and with what seems like arbitrary unpredictability)  heaps great good fortune onto some, horrendous misery onto others, and pretty much ignores everyone else?  

Are you talking about a god who can, at his whim and will, step outside the laws of the universe and do anything he chooses,  including acts of magic,²  and granting special favors to those who bribe him with prayers and adoration, or destroying someone's life in a momentary fit of anger? 

Are you talking about a god with an ego so great that  he demands our worship and a self-image so small that he demands our obedience -- a god so weak that he needs our help to punish the unfaithful -- a god so weird  that he murdered his own son as an expression of love ²  -- a god so angry, hypocritical, and unforgiving that he preaches forgiveness and, at the same time, is still punishing people today because a long- dead ancestor (Eve) ate "fruit" from a forbidden tree --  a god so ridiculous that he abandons and condemns to never-never land literally billions of humans simply because they never got sprinkled with or immersed in water by the correct holly man?   

Are you talking about a needy, self-centered, brooding god who offers free will and then demands obedience to a set confusing and self-conflicting rules that are impossible to comply with?   Are you talking about a masculine god who created women as sex slaves and servants --  a god so small he can fit inside of a single religion or into a single sacred text -- a god who demands that we murder people ²   simply because they believe in a different religion?    Are you talking about The Great God Money,²   the most revered deity on the planet today?  

If that's your definition of God, then the answer is no.   I don't believe anything which fits the above description could possibly be God.   I'd sooner believe that the tooth fairy and the Easter bunny were living in my attic and having an affair with Miss America.

The Faceless Face of God:   

When you ask, "Do you believe in God?" are you are talking about the source of all creation -- a source and a consciousness that transcends human understanding?   Are you talking about the sum total of all that is --  the ever-flowing essence of everything --  the central cause of all creation,  from the minutest to the greatest -- the source of everything we are and everything we experience?

Are you talking about "An Infinite Source"  who/which/that  neither rewards nor punishes -- a God that has created a set of invisible laws ²  --  laws that are as immutable as the law of gravity, laws that we each can intentionally use to create our own personal experiences (or ignore at our own peril)?

Are you talking about a "God" that is unknown and unknowable -- a God that expresses itself in a mysterious form of consciousness-- a "God" that expresses itself as freedom, love, joy, and beauty -- a god that manifests itself as the sum total of everything we are aware of in what we call the physical universe?

 Are you talking about a "God" that manifests itself in each of us as whatever we choose by our thoughts, beliefs, emotions, words, and actions ²  --  a God that allows us complete freedom to unconsciously create pain and misery or to consciously create love, joy, and beauty in what we call the physical world? 

 Are you talking about a God that we are each an intimate part of --  a God which is that mysterious part of ourselves we refer to when we say "I' of "me,"  

If that's your definition of God, then the answer is "DEFINITELY YES,  I DO BELIEVE IN GOD!"
