What is Time?

Is a linear measurement, a method of measuring  and controlling, periods, distance and circumstance.It cannot be manufactured or destroyed it is however expendable. Time is the basis on what all circumstances  are controlled. All events can be traced back to a particular time and to a certain extent future events can be predicted. To indicate just how heavily time controls us, let me give you some examples. The earth as formed Hundreds of Millions of years ago nobody knows for sure but certainly a long tie ago. Since then it has systematically gone through specific changes to develope from what in the first instance can only have been a lifeless piece of gaseous mud. over time, hundreds of millions of years there took place gradual changes. We say it evolved into the world we have today. All we know is that it took time. It is impossible for the mind to take in the enormous amount of time it took, the only example I can give is of a one fingered clock that is housed in a building on the southern lip of the Grand Canyon in the USA This clock is  eighteen foot in diameter and it assumes that the canyon dates back to as near the beggining of time it is possible to get, On the face of tis clock is marked the various stages that the world has had to go through. What is quite startleing is that when the finger of the clock is completing it's sweep, the last 3 seconds of this sweep is when man appeared on the earth. Now this indicates quite well the fact that the difference between the earth and living creatures is that the earth and the universe have all the time they need, we do not. Take man as an example, he has an average life span of seventy years. This equates to 25,550 days,= 61,3200 hours, = 36,792,000 minutes. In this period of  time, we are expected to study for a good  education.. Keep down a worthwhile job, bring up a family and retire gracefully before moving on. Where on earth do we find the TIME?
