Can anything exist for an infinite time or outside of time?

The beginning of time was the beginning of the universe which was the big bang. That was when space, time and matter came into being.No prior time, no concept of infinity, nothing. Trying to grasp a infinite amount of nothing means time. No, it is impossible for us to grasp anything prior to T=0. The was nothing, and now there is everything. Words like preexisted, existed, infinite, do not apply since the beginning is where all these concepts take meaning.
