I don't think there's any doubt that God is the only creative source, so in that sense only God is our Father. All that remains is for us to grope for Him, which is what He wants, hoping we will find him because we are family, only lost members, sheep.
Acts of the Apostles 17
26and He made from one
man every nation of mankind to live on all the face of the earth, having determined
their appointed times and the boundaries of their habitation,
27that they would seek God, if perhaps they might grope for Him and find Him, though He is not far from each one of us;
28for in Him we live and move and exist, as even some of your own poets have said, ‘For we also are His children.’
29“Being then the children of God, we ought not to think that the Divine Nature is like gold or silver or stone, an image formed by the art and thought of man.
God took the initiative to wake a desire in the Athenians, being His children, hoping they would seek Him.
