      Scientists currently think the universe is about 13.79 billion years old, give or take about 37 million years because measuring numbers that huge needs a little room for error.

      There was probably no time for anything to happen in before the big bang created time and wound it up with all the other dimensions though, so it might be fair to say that the universe has technically existed forever 🙂
