Yes, the continuation of space to exist is time, and thus it is called spacetime, time being the 4th dimension.Yes, in your '3D only' view, it looks like that. But that is a limited view that has little to do with reality. Existence simply exists. Spacetime does not 'continue to exist' because all 'continuing' is within it.
Also, you are talking only about the human experience of time. That is primarily due to entropy effects that mean we remember the past an not the future. But the future 'exists' in the same way as the past 'exists'. Both, together with the present and all of space during all times is what spacetime is.
Also, you seem to not understand how time can differ based on observer. That things like gravity and velocity can affect relative measurements of time.
The point is that time is part of physical reality. It isn't something different. It is an aspect of the geometry of existence in the form of spacetime.
Just like to measure space you need a stick calibrated to meters or feet or whatever unit of distance. So?
I cannot 'watch' a time interval of a millisecond. It is physically impossible for humans to detect such time intervals. But that doesn't mean they don't exist. And such time intervals represent 'continuing to exist' just as much as seconds or hours.
Don't get confused between the psychological experience of time and what time is.
No, it is actually much more subtle than that. It means that if you look at the universe from a 'comoving frame', then the number of cycles of certain wavelengths of light will be a certain amount. That is all it means.
What is real is 3D space existing as spacetime. There 3D space and 1D time. The future is determined by the present events, the present was determined by past events.
I am not talking about observers of anything, just the reality of existence.
I've explained what time is to you, it is existence continuing to exist.
I am not talking about an observer of time, once again, for example, if this planet is said to be 4 billion years old, it just means it came into existence 4 billions years ago and has existed until now. It is so simple!
