HI Peter and welcome to the Board..
I find your question "short-put", a bit unconscious... but never the less interesting. As if your awaiting just a short a answer as you formulated your question.
I
can share "my take on it", but before I do I would like to generate some general heat within your head, love. Simply by asking a few questions to you.
A Person, you encounter, a stranger .... you dont know, they have never said a word to you, you know nothing of them....
Is this person
intelligent or is this person daft? You can`t touch "intelligence", its not something you can hold, see, touch, smell. We have to use the methodes which have been "created over time" inorder to measure "it". There had been many many thousands of years ago...
where these technics of measurements were not available. I think you take the knowledge of such, for granted right this min.
But what about this perspective. => Someone whom you feel may be intelligent, may be completely daft ...compared to someone I may think is intelligent, or other way around, eh? So now we are at the divingbord of.. "different take on thing" ie. different Realities...different perspective..
The very fact that you asked the question to begin with, or that it was prompted for you to ask is your innerself "begging for
Knowledge".. but Dear, you have already identified that "BOOKS" will be BOOKS, handwritten by man and they are certainly sold best due to ingrediant of highest quality of provacation =>
Drama ..
So I hand it to you... you are infact intelligent. But please keep in mind not anyone, simply not everyone can be "an author" either. An Author is "inspired to write"...right?
As Example: You know a car runs because its tanked with Gas, has a motor and mechanical parts, its not being "inspired" to do so out of seemingly nothingless, its
mechanical and thats why it has "limits in its operation".
So lets get to your kern question. I believe several have tried to explain their take on the subject God.You want "proof"? Yet inorder to even first be able to "see", "hear", "touch", "smell" or even "taste" God, you have to be willing to let go of your "
mechanical way of thinking". Simply because it "
limits" you. Just as a car can never fly.
You will (and I can promise you such...) will "
continue" to have
plenty of opportunities to achieve your proof of God, providing you are willing to return to your true nature of "listening". Do your homework, open your heart and you will "get it"..

There are many many lessons as to what God is, and the reason why there are so many ways to attain the knowledge is simple. => Because there are many many many different Souls (
Students at different levels of learning just as it is in gradeschool, jr. high and high school, college, univer. )
So if I were to tell you go look into the mirror then you at me, your neighbor, the person in another country , put them "all together" and you will see GOD =>
you would call it blasphamy!
Right? So now we are back to the "perspective issue" I mentioned above. A really nice testimony for me to come to the basics of understanding had been called "Conversations with God"...You can google it.
Maybe once you`ve broadend yourself through that by means of the basics...you`ll be ready for the next step.. =>ALL of Bruces beautiful testimony. You are clearly ready for it.
Can you proove to me that there is NO GOD? Maybe the soul whom said the word "God" for the
very first time was illiterate and really meant "DoG" (god spelled backwards) and imagine how many times you`ve then been mean to God, simply by yellin at your "dog!"

Hugs
