As an alien observer from a far one might wonder how humans might want to exploit my knowledge, technology or even the flavour of my flesh (if I have any). That's assuming that alien has mostly inquisitive intentions.

Alternatively, aliens with more exploitative intentions might be just as bad as some humans are. Perhaps, because we are still in our technological infancy we have little to take advantage of for now. Even less to warrant the work/energy expenditure required to plan a visit to our neck of the galaxy.
