I think it's more likely that any sufficiently advanced civilization capable of monitoring earth, relatively undetected, has evolved beyond the types of problems that compose the way we view everything. Assuming that mundane explanations have been systematically and thoroughly refuted I'd posit we're the curiosity of the extraterrestrial version of something along the lines of a zoologist, student, or voyeur.
