It is science fiction because it depicts an example of a phenomenon that is not fully accepted by mainstream science. In this case, the phenomenon is E.T., because it is an extraterrestrial life form, and extraterrestrial life forms are not proven to exist, they are only speculation.
You can apply that we all need to be much more careful and to stay positive we can also try not to touch everything, because I know before corona virus I used to touch everything.For example I used to touch everything at the stores. Clothes, railways, unnecessary walls and the counters. Know I just don't touch anything.
Hope this helped.
