It is your problem. I have no problem to know, what I saw mine God in the facts like "1+1=2" right from my beginning. It is like the Sun for new born baby: the baby does not know the name of the Sun, but already feels its actions.
The problem is, I believe you. You feel the presence of something. Something that you can't understand, something that is beyond you. A presence that you are certain exists. That inspires you, provides moral guidance. It provides answers when you pray. It can make you feel loved. This presence exists and I certainly wouldn't deny it's existence.
While I can't speak for everyone, I suspect everyone feels this presence. Accepts its existence on some level.
Whereas you call this presence God and worship it, I see it as the work of our subconscious mind. The subconscious mind is larger, faster, more knowledgeable than the conscious mind. The subconscious mind provides our perception of reality, our feelings, our inspiration and even answers to problems and questions we have. The subconscious mind can do for you everything that God does for you.
So why choose the subconscious mind over God as an answer to this presence you feel? Because while we can't be consciously aware of our own subconscious mind, we can test it, validate it, understand how it physically works. God on the other hand can't be scientifically validated. You can imagine or create or envision God to be whatever to wish/desire and do so without any validation what so ever. That's why there exists so many different versions of God.
Yes, your God is the true God, so is everybody else's God... What? you want validation? You don't need validation, you have faith in this presence that you know exists. You can feel the truth of it can't you?
I felt the truth of it too, except I questioned the truth of those feelings and found that the facts didn't care about my feelings. The truth is you feel the presence of God, but that's not the fact of God.
