Disturbed Timeline

Where do humans come from? Where are you going? Why does it exist? What is the meaning of existence? What is the time? In a sense time is nothing but the rotation of the earth! If there were two big hands in the universe, they could stop the earth or even the entire universe! Does time still exist? (Mainly focused on cities, interspersed with technology and low-level ancient martial arts in the mid-term, not immortality.)
