I would love to adopt an alien, like they did in E.T. It would be like having a pet but even better. Everyone has a pet, but not everyone has an alien. You could ask it all about its home planet and perhaps learn some of their language. You could see if it has any special capabilities that humans don’t have. The one drawback would be that you’d have to hide him from the government, lest they take it away to conduct tests. And you’d probably feel a little guilty that you were essentially kidnapping it from its home planet and thus depriving it of a childhood there, even if it wasn’t your fault.
Luckily these things are all explored in the film E.T., thus leaving us satisfied and touched. This is exactly what sci-fi is good for. It teaches us about improbable eventualities without us having to live them ourselves.
