Hmmm. I'll try to clarify what I mean. So, usually, when we talk about things existing or not, we refer to an object and a certain point in time (did it exist then or not). It's not at all obvious to me what it means to generalize this to "one point in time existing at another point in time", or a point in time just plain existing.
It does get confusing trying to talk about time. What I am saying is that yesterday did exist but does not anymore. It is gone and can never come back. People think we can jump back in time but that really doesn't make sense because the past isn't there (or anywhere). In order to make the past happen again, you would have to put every particle back in its previous spatial location with the same energy level and direction. It's not possible.
