Does “Spacetime” imply that all of time exists simultaneously in the same way that we perceive the dimensions of space to exist simultaneously?

I’m trying to wrap my head around this. I perceive time as though the present moment is a wave I’m riding through space and experience. Does Spacetime, as presently understood, suggest that time is more likely an ocean that exists and is “real” stretching off towards the horizons? In other words, is the present the only thing that is real as we traverse the dimension of time? Or do the distant past and future also exist, despite my inability to experience them, just as distant points in space do?

The past and future exist relative to your current place in space and time. Your specific version of time, relative to you, is all you’ll ever experience. You cannot travel time in the sense that you can visit your own past or future, but you can visit someone else’s future, but that will still be your present.
