A Spiritual Force
Space, time and matter were made by God, as it is written in the beginning God created the heavens and the earth.
He exists outside the vastness of space, time and matter, but is also present everywhere and filling all things.
He's made up of three Godheads who are one in essence, the Father the invisible one, the Son the mediating physical body of the Father, and the Spirit preceding from the father and descending upon the Son. The only way we can know the invisible Father is through his son Jesus Christ who walked the earth with us, and we can only know Christ through the Spirit that descends upon Him and us.
As He's outside the confines of the matter of our brains, the molecules of our brain and therefore our body cannot be trusted in any way to know how we ourselves were formed if we are merely randomly made molecular structures from billions of years of evolution.
How can we trust our own thoughts and theories, how can mere matter create such emotions as love, anger, jealousy, hatred, envy, determination, faith and so on, and how can we know and trust these feelings if we are merely molecular structures?
Gas, liquid and solid which make up matter cannot make itself if in the beginning there was nothing. It doesn't have the capacity or capability to create itself, it requires something outside it to create it.
Our brains can never understand the workings and complexities of God, if I understood fully the greatness I would not worship Him. He is above and beyond my understanding.
It is with a spiritual force that only a true loving, all powerful God has can help guide us to see and know the truth of creation and life, and the right way to live and to exist.
