But the universal space itself has no notion of this.
Hmmm, so what does the universe have a notion of?
Nothing. That is like asking what do mathematics have a notion of. These are functions that require no conscious participation.
IMO, time is a human invention to record the duration of events.
You surprise me. CLOCKS are a human invention to record the passage of time.
Well yes, both time and clocks (measuring devices) are human inventions to symbolize observed natural phenomena of chronology. “Time” is a human symbolic term. Clocks are measuring devices which record the emergence of time in parallel with chronological change.
Time was there all along. Heck, how could matter have coagulated from energy after the “Big Bang” if time wasn’t happening from the beginning.
No, that's not correct. Time does not exist until it is created along with chronological change. Time began with the Big Bang (t=0). Before the BB there was no time,. only a timeless permittive condition.
There is no time in the future, it has not yet been created by the present. If time existed on its own it should be measurable, but that is not possible. You cannot measure time with time. You can only measure physical duration with time… i.e. the caesium clock, which is only usable due to it’s incredible vibrational precision.
Caesium: A brief history of timekeeping - BBC News
The clock mechanism counts a second each time it swings. Quartz plays the same role as a pendulum, just a lot quicker: it vibrates at a resonant frequency many thousands of times a second. And that's where caesium comes in. It has a far higher resonant frequency even than quartz - 9,192,631,770 Hz, to be precise.Oct 4, 2014

But a caesium atom does not in any way describes time, it describes the vibrational frequency of caesium.
Consider; what is a fundamental unit of time, how long is a moment? There is no answer to that question, because time does not exist until it is created by a momentous event.
The notion that humans somehow created time, because we developed concepts that define and measure time, seems as out there (and ego centric) as thinking consciousness is something outside of the human body, rather than an emergent result of your body’s evolution and biology.
No, that's not what I am saying. Human do not create universal time, the universe does. Humans create their own individual time-lines, i.e time relative to events related to human existence.
What we have named time is our observation that certain events have regular durations or recurrence. Time is a mathematical term of a natural function. The orbit of earth around the sun is a function of time. The universe doesn’t know that, we do and we have symbolized it.
