Time Is Artificial

So I'm Trying to Expand Upon my Theory that Time is Man Made, or Essentially Artificial.
The definition of time is: The continuum of experience in which events pass from the future, to the present, to the past.

Of course I can't disagree. However, my issue is that not only do each of us perceive time differently, but the literal "time" (One o'clock, two o'clock, minutes, hours, days, weeks years, and so on and so fourth.) are merely man made methods of organization and classification that have been so deeply and thoroughly engrained in us for so many "centuries" that nobody realizes we're all measuring our time the "man-made" way. Nobody stops to think - what does time mean to me? How does time feel to me? The bottom line is, we are all programmed to abiding by and basing our existences on this manufactured version of time.

I say we burn all the calendars, get rid of the clocks, and make the best of time rather than trying to organize it. The sun rises, the sun sets, the weather changes in undeniably evident patterns, and all living creatures age.

Why not let these facts be our only observation of the progression of time?

I mean, insects don't have clocks,
why should we?
