Anything before God?

Here is another question that was asked by a 9 year old visitor to my old website:

Ok first I know that GOD was here before anything, but how? I mean it's just so confusing.

     For a thousand years in thy sight [are but] as yesterday when it is past, and [as] a watch in the night.
          -Psalm 90:4 (KJV)

     But, beloved, be not ignorant of this one thing, that one day [is] with the Lord as a thousand years, and a thousand years as one day.
          -2nd Peter 3:8 (KJV)

Time was created by God. Because God is eternal and outside of time, to him, one day is the same as a thousand years. The Study Bible I use (The Evidence Bible by Ray Comfort) has a very good explanation for this:

    The question of who made God can be answered by simply looking at space and asking, “Does space have an end?” Obviously, it doesn’t. If there is a brick wall with “The End” written on it, the question arises, “What is behind the brick wall?” Strain the mind though it may, we have to believe (have faith) that space has no beginning and no end. The same applies with God. He has no beginning and no end. He is eternal.
    The Bible also informs us that time is a dimension that God created, into which man was subjected. It even tells us that one day time will no longer exist. That will be called “eternity.” God Himself dwells outside of the dimension He created (2 Timothy 1:9, Titus 1:2). He dwells in eternity and is not subject to time. God spoke history before it came into being. He can move through time as a man flips through a history book. Because we live in the dimension of time, logic and reason demand that everything must have a beginning and an end. We can understand the concept of God’s eternal nature the same way we understand the concept of space having no beginning and end—by faith. We simply have to believe they are so, even though such thoughts put a strain on our distinctly insufficient cerebrum.

It is natural for us to think that everything has to have a beginning (and an end) as we are born into the dimension of time. But God, who created time, exists outside of time, and is not subject to it.
