Past and future do not exist

Time with past present and future do not exist.  Division of time into years months weeks days hours and yesterday and tomorrow are all man's creation.  Just go away from earth, there is no day and night difference. 
Man who invented clock and calendar invented time for his convenience.   Empty space with everlasting existence remaining beyond all galaxies is the only being from which everything emerges, functions and at last dissolves into it.
Can anyone ever say exactly which is the first day and which is the last day? No one can say.   It is not because people do not know it is because no such things exist.
Imagine that the whole universe destroyed.  Or go back or imagine the time when no human beings exist on earth.  Who is there to calculate or interpret time?   Earth's rotation of itself led to day and night.  Even now if you are living in north pole or south pole, do you think that you will have day and night.
Tomorrow becomes today after one day and the same becomes  yesterday after two days.  Thus yesterday is not always yesterday and today is no longer today. 
Man with all his power can never go back into past to rectify his wrongs and loss.  He is never guaranteed for  his future life. Live ever peacefully and blissfully as a man of no past and future.
