What is God? I can only tell you that there is too much organization in the universe for this to have happened only by chance. If there is a design there has to be a designer.

In short nobody has all the answers on what God or the creator is. We can only attempt to comprehend what God is by what we can see and experience, we are limited by our 5 senses.

There is no seperation from the act of creation (us and the universe) and the creator. So in a way you are part of God, God is in you and you are in it.

The question you are asking has been asked for thousands of years and many religions have come and gone based on their preceived impression of what God is, their own versions, but in reality they never knew what God is and only attempted to grasp that which cannot be understood currently in our limited physical form.

The title of your post is the answer to your question

No - ONE can answer this!

This is one of the secrets, nobody knows, it is beyond our ability to comprehend.

I would focus on why are you here, what are you supposed to learn, what are you supposed to experience. If you can answer these questions you will be closer to answering your question than you are today.

As far as any belief system having all the answers, the truth is without label, you are free to seek the answer without limitation.
