Really? Every aspect?
Can you logically talk yourself out of having to go to the bathroom? Can you explain how much logic and thought it takes to keep your heart beating steady and your food digesting?
I can't even logically tell you how I make a simple motion. It's some kind of cascade of chemicals and neurons I'm told, but dang... I just think: "Move arm" and it does. I don't even have to think about beating my heart.
In fact, without a working definition of "God" I really can't come to that conclusion. Perhaps if you could offer some properties of this "God" I might better recognize its existence.
One of it's biggest properties is that it all lies where human reason and logic fail. It is the thing that is unsullied by that.
I'd like to take a shot at that, if I may.
I would direct you to start by looking at yourself. Not merely at the surface you, the analytical rational you, but at the deepest you. The you that has existed since your earliest memories of being you. The you that is distinct from every other thing and yet connected to every other thing.
This can be harder than it sounds. It takes a great deal of courage.
Many people only look that deep when they've reached some personal crisis; others when they are terrified for their lives. It is at that core, at the essential you, that you will find God, at least that's where the rest of us have found Him.
He has all ways been there, and you have all ways known Him.
