Well I'll make an attempt to reply back on the original topic.

Mac, if everything were always happening, I don't know how to conceptualize that because of my human perspective of only being able to experience one moment in time, i.e. "now".   Unless...if there was a way to pick an event and only focus on that experience then that would be more akin to what I said earlier, that I wish I could relive certain moments and experiences. 

I do believe we have everything we've experienced "recorded" inside us but the problem is not being able to access it.  For instance, I remember a few specific things about very special moments in my life but of course I can't recall every single moment of them. 

But part of me is satisfied and maybe happier that I'm not reliving things, even good things.  I think there's so much value in growing from our experience of time passing.

We really are never the same person from moment to moment.  I know that's an exaggeration but what I mean is, we are always slowing changing because of our experiences, feelings, thoughts, etc.  I can remember many times in my life where it's sad that I had to grow and change from the person I once was.  For instance, I liked the person I was way back in the early days of my marriage, but because of a bad marriage and abuse, I changed.  Which wasn't a conscious decision per se, it was actually survival and adaptability and it happens subtly.  When the storm has passed one day you realize you're not the same person and you never will be.  But mostly the changes are wonderful and I'm grateful for being a stronger version of myself.  But part of me wonders what life would be like and what I would be like had my marriage been wonderful and loving and we were still together.  Not because I miss him!  But because in a way, I miss my past self.  It's only a curiosity, not something I actually want!

So I guess if I had to choose between the way things actually are and your what-if scenario, I'm very happy for the way things actually are.
