This question has a false premise. It assumes that God was, in fact, created. For something to be created, it must have a beginning. God does not. I hesitate to use the word, “eternal”, but I will say that God *transcends* the time and space limitations of this universe. This is not as unscientific as it may sound. Many scientists postulate a limitless “mother” universe which gives “birth” to finite “child” universes like the one we find ourselves in. That sounds almost religious, doesn’t it?
I write, as far as I can tell, because writing is a black sheep sibling of prayer, an urgent struggle against a bad connection, intent, hopeful, innocent, never quite good enough.
