@RyanMelcher Technically time as we know it began whenever God created the universe, so before the universe existed was ‘before time’ and certainly God existed prior to the universe. When the Bible says God did something ‘before time’ it just means before He created the universe. That is one thing that distinguishes the God of the Bible from the pagan gods - the pagan gods were all part of the universe - the God of the Bible created all things, including time.
How exactly ‘time’ works in the spiritual realm or if outside of the laws of physics we know in our universe it even does exist is a question I am not sure we can answer.
Finally, there is the scriptural contention, and of the three it alone makes sense: the universe was created by an uncaused First Cause greater than itself. Time, space, and the universe have not always existed, but God has always existed, and God’s existence is the cause for the existence of all else that exists.
