I was born in the Now, as everyone was. What time was it when YOU were born?
7:38 pm on Jan 9, 1979.
When you were born, it wasn't now, it was then.
All you are doing is saying that in the moment that we experience something, we call that moment "Now". But once that moment has gone, it ceases to be now. All you're saying is "The moment we experience something is the moment we call 'now'. We live our lives in a series of 'nows'."
Ultimately, you end up repeating yourself, in saying that the moment we experience something is always 'now' to us. You don't seem to realise that time passes, and what is currently NOW will, in five minutes time, be "THEN."
You aren't being born in the NOW. You didn't say your first word in the NOW. At the moment you said your first word, it was NOW to you, but time has moved on, you are no longer saying your first word, and thus the point where you said your first is currently a THEN. And it will always be a THEN unless you discover time travel.
The system of measurements are real, but they are not Time. Because of standardization, we all agree that a minute is 60 seconds in duration, but again, '60 seconds of duration' is not a measurement of Time, but increments of the measuring device itself. Such a device could have 75 increments, or any other arbitrary set of increments.
Then what is it measuring?
Yes, a second is an arbitrary unit, but then again, "duck" is an arbitrary label. We could call a duck a faschnoozle, and it would change absolutely none of the qualities the duck itself has. Likewise, we could choose any arbitrary period to measure time in, but time would still exist. It would just be a different label.
So this answers your question about subjective illusion. The illusion of Time is confused with a standardized measurement system.
No it doesn't. All it does is show that you are confusing the arbitrary nature of the units we use to measure time with the actual thing being measured.
I could make exactly the same argument about distance, but would you say that your height is an illusion?
The question of Time seems to center around whether Time is a reality that is embedded into the universe, or whether it is merely conceptual. 'Time', however, can only exist when we have a system of measurement to apply. Please remove all systems of measurement from the discussion, and then show me where/how Time exists as a concrete reality. Without such a system of measurement, Time ceases to exist.
So are you saying that no time passed before there were Humans who measured it?
