Does Time Really Exist?

I was posed with the question, "Does Time Really Exist?"...

Time is only a relative item in our existence. Time is only important for synchronization of activities such as meeting someone, getting to work, or executing a space shuttle liftoff ...

Beyond that, time really doesn't exist.

Think about it. When you're in your groove, doing the thing that you love, time has no relevance. You've probably noticed that when in such a state of mind, deeply involved in your "thing", that time seems to either pass very slowly, or very quickly. Your world, when in such a state, is only bound by your immediate experience.

How many times, when in such an engrossed state, so you look up to reference the clock and say "oh my God! It's mid-night! I got to get to bed!" ? Plenty, I'd guess. But did it matter that time seemed to jump to some later point beyond your own realization or relative point of view? Did it matter to you at all that sub-tasks within your activity took specific periods of clock time? Probably not.

The converse happens too. When you look up from your involved state of being to see that the clock has barely moved at all? Feels like a secret blessing, a personal gift given to you by the clock...

Time is relative, and is only a marker by which we involve ourselves with others.

If you grew up unaware that clocks existed, unaware of days, months, years - in a log-keeping aspect... how OLD would you claim to be? You would see yourself in the light of physical aging, and only from your perspective. Would you be 50? or would you be 11?
