And yet we know there is God ... so not an absolute statement. God said 'let there be light' and some interpret that to mean intelligibility.God is unknowable ...
It's a pity your dogma declares that. Other religions say otherwise, mine, for example:... all doors are shut to that Most Great Spirit.
"If any one love me, he will keep my word, and my Father will love him, and we will come to him, and will make our abode with him." (John 14:23)

In the Orthodox Patriarchies, there is a distinction between the Divine essence (ousia) and the Divine act (energeia) – between who God is and what God does. The theology arose in a specific climate, and was not entirely endorsed in the West, although latterly the dialogue has been a lot more fruitful.
In lay terms, God's essence is incomprehensible, but He can be experienced through his energia, His effect on and in the soul – spiritual growth. (The Christian idea of spiritual growth is vastly different from the common concept of the term.)
The East holds that God is unknowable in His essence, but can be known – experienced – by His works in the soul (and some might say known on an even broader scale in the world), but such experience changes neither who/what God is, nor who/what the one experiencing God is.
Just as a plant grows by the experience of sunlight, soaking up the light and warmth, but does not become the sun, so a person who 'soaks up' the warmth and light of God and grows spiritually does not thereby become God.
(The doctrine of theosis, or deification, is a nuanced doctrine – essentially of adoption – that takes some explaining.)
In the Latin west, the ousia–energia distinction as a real distinction in God was rejected, opening up a can of worms with regard to compartmentalism, polytheism, subordinationism, and all manner of other isms. In very simple terms, God is what God does, God does what God is, but again care need be taken else we drift into pantheism. As the saying goes, 'It is the Nature of the Good to communicate Itself'.
The whole thing kicked off in a dispute over hesychasm, the Greek practice of 'stillness', founded on Bible and particularly the Psalmist's: "Be still and know that I am God" (Psalm 45:11 according to the Cat. numbering) Whatever, the point here being, the Psalm does not say "Be still and know the works of God".
