When we say the word time, what do we really mean?
Is time just a measurement of day and night (seconds) or is it an evidence to the existence of life.
When we talk about time we talk about so much more. With time, life becomes meaningful and brings reasons. It's what makes us plan out our daily activities, what makes us move, what makes money meaningful and what makes humans special in all ways.
As physicist we understand that time is one of the three dimension of space which was formed from the bigbang.
Conclusion
Well I perceive time to be the only unit of life or the true unit of life because if time is irelivent the reasons to live becomes unreasonable....
