When, why and how was time ever created.

How was time on earth created?
when did man first decide this is day 1?
there shall be seconds and minutes and hours and days.
with weeks and then months and finally years,
who decided this was how time should be?
who even named it time?
Who would have thought that 1 person would have such an impact on this earths timeline.....
so before the man who created time,
how much more time was before him? 
her?
it?
was it even a thing?
whatever it was,
was definitely onto something.....
what was the need,
the necessity for time to start? 
Most of these questions,
i know they're no answers,
but they are all still swimming in my mind.
i know all these answers i will never find,
yet still curious to know whether there are answers out there just waiting to be  found.....
