It doesn't mean that "existence has already reached a later point in time, of the infinite future time available, where heat death has been experienced".You see, you speak of an infinite future time available, but don't comprehend that always having existed likewise means that an infinite past time has already gone by. You're claiming it's always existed, yet treating it as if it had a definite starting point.
And again - how old is something that has always existed? There's no way to answer that. Yet, science tells us the universe has a finite age.
