So I take it that you believe that before created he was alone in a void. Black nothing floating around in empty space for eons of what ever he counted as time.
To speak of "before creation" is intrinsically problematic because terms like "before" and "after" are rooted in time. Before everything was there was no space or time and there are no adequate terms to speak about it.
Though, of course, Christian theology instead has typically spoken instead of the idea of divine transcendence: that God is beyond all things. God is fundamentally and radically other than everything else; God is neither bound by the spacial constraints of the universe--even the spacial constraints of a possibly infinite universe or even an infinite multiverse--nor the temporal constraints of the universe. God is wholly other, and hence historic Christian theology has asserted that the Divine Essence is unknowable, ineffable, incomprehensible: we cannot understand, know, comprehend, or effectively speak of the Divine Essence itself because it is so entirely
other. We have instead attempted to speak not cataphatically of God's nature, but apophatically; that is rather than saying what God
is, saying what God
is not. Because what God is we cannot say and cannot know; indeed even to say "God is God" misses things because our language is abysmal and tiny. We can only know God through His acts, or in Greek,
energeia, His energies. We know of God because of revelation, and by revelation God makes Himself known most importantly and chiefly the revelation of Himself in the Incarnation; for as we read in the Gospel of John "no one has ever seen God, but the only-begotten Son/God, who is at the Father's side, has made Him known." (John 1:18)
So in answer to your question there was never a time "before creation" but rather God, in the utmost sense,
is. There was no void, or empty space, or eons; there is only God--but the creative act births into being a that which is not God; and this that which is not God has time and space and the concepts of time and space only make sense in this universe of space-time. And most importantly, no God has never been alone; because God being Holy Trinity is the inter-penetrating loving and self-giving of One and Other; namely the Father, the Son, and the Holy Spirit. The Father has never been alone, because from all eternity He has a Son, begotten of His own ineffable essence, who is God of God and God with God; but one and the same God. There is no emptiness or loneliness; there is only the immense love that flows outwardly from God to God, never selfishly, but always outwardly always kenotically*.

*from the Greek word kenosis meaning "to empty" or "to pour out"; it is the word used by St. Paul in Philippians 2 when he writes that Christ "emptied Himself"; used here to speak of the outpouring of God's Self in the perichoretic relationship of the Trinity, that of the Father pouring Himself into the Son, and so on and so forth.
