"Xenobiology."
Don't you feel overwhelmed by this scientific field? I've seen it in movies and read about it in sci-fi books, and I always wanted to be a xenobiologist. Then, I saw Ridley Scott's Prometheus & Covenant and abandoned the idea, as it proved too complex: there is no way that the evolution of the "alien" creatures can be explained rationally; only time-traveling can account for all the events happening to the creatures in the film, and how they evolve to different species, different kinds of impregnation, etc.
So much for xenobiology, now I want to be a time-traveler!
