Return to campus, study for a while, find a job, and return to the research track. Then, on this planet separated by an unknown number of years and light years, live out the simple yet fulfilling life my parents hoped for.
At the same time, take on the identity of an ancient person and experience future human science on behalf of my peers who vanished into the long river of history, thus fulfilling the life regrets of many classmates and mentors.
I can also secretly write, under the guise of fantasy literature, about the arduous pioneering years of human ancestors on Earth, perhaps already lost to time.
If luck is on my side, I might even start a family, spread my branches, and fulfill my father's greatest dream—continuing the family line.
Though my unknown brother has already fulfilled my father's dream, there's no harm in doing it again as a filial son, is there?
Even though my father will never see it again, just for peace of mind, it's worth doing.
