Is there a specific beginning or end in the water cycle? why or why not?

I don't think the water cycle has a beginning or ending because all the water in the world is always in various stages of the cycle. It's kind of like asking if a circle has a beginning or ending.
 At the very least, I can't think of a specific 'beginning' or 'ending', although I suppose there is an argument to be made that percipitation is the ending and evaporation is the beginning. 

Heyhonestly, probably not. humans have always had a tendency to waste things. whether it's food, cosmetic, infrastructure, or our abandoned constructions,the landscape is littered with the refuseof man. archaeology wouldn't be a developed discipline if humans didn't leave things behind. in a way it makes us human

hope it mark me as brainlieast.
