Long ago I was a metrologist, one who deals with the science of measurements (length, mass, time, temperature, luminescence, and amount of substance). I specialized in time measurement during most of my tenure. We measured time to within +/- 1 part in 10^-13 seconds. Now it is measurable to with 1 part in 10^-17 seconds. Time is measurable to a higher degree of accuracy than any other measurement. It is an artifact of our universe as we know it. We do not know what happens to time inside a black hole, for example, nor its relevancy from the perspective of other dimensions. Tens of thousands of reports from NDE experiences argue that it does not exist there. I agree that despite GPS and atomic clocks we do not really know Jack about time.

I have read that time is like a river, you could never step in the same river again because where you stepped before has moved downstream.

Both that night and day cycle, allowing for time to sleep, rest our weary bodies and the annual cycle of the seasons preclude a need for urgency among those fearful of what the night or the winter might bring. Now lost to us except when the power goes out.

But in universal time since the Big Bang, human evolution that you describe is minuscule when compared to light years.

I think you are referring to our penchant for the daily news of how things are going and how we do not pay attention to the course of history and the surprises, like COVIT-19, that await us beyond the bend of our perception. And our corporate penchant for quarterly or annual profits over long-term consequences of corporate behavior.
