Both causality and the "flow" of time are ultimately artifacts due to the fact that a "universe", by definition, is something thay starts out in a highly-ordered state and evolves away from it. The basic laws of physics are time-symmetrical, at least in a practical sense - they do not involve any distinction between "cause" and "effect".
