Good job Irina. Below I have made some corrections. Hope this helps.

Life is theatre (is a play)?

Is there any possible flow of life nowadays (not sure what you wanted to say with this), when life doesn't only reflect the previous situations of an existing matrix, but takes its own way of development, determined by real moments of today, by present events, feelings and intentions of people?

Or is the whole life is really just a play and people are the actors?
