Time expression before clocks

They had a specific time (amounts)?

The body starts just one cell, which means every single cell is the same. So all cells are being controlled by the same rules and patterns. Of course, you know that...

And, by the way, clocks were invented a little ago though human history, so expressions about time such as 'a while', 'a moment', 'at', 'several' something like that have existed before clocks, which means those expressions had indicated a specific time in the past.

So, 'right' has the meaning of time because humans could see time like a direction before clocks. Humans before now we had left all these on words. Wow, amazing. :) Clocks also have some secrets, now I am trying to figure it out.
