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?
We are all foolish sinners saved only by grace & we can all use a little guidance sometimes.
