I think your problem lies in the fact that your thoughts are, along with every other human for that matter, tied inextricably to the physical laws that persist in our "universe." There is no reason to believe that all of these, most especially time as we understand it, existed before the big bang. So any thing that existed previously would be nearly impossible for us to understand. Also, I think the point is made nearly moot by the scope of the known universe. Even most stars won't live long enough for their light to travel all the way across it. For such puny and short lived creatures as us it is for all intent and purposes "infinite" if not actually so.
