If anything it would just be one of their Von Neumann probes looking to fuel up, probably from Jupiter or Uranus. Maybe it would send some pics of us back to the home world where they might say "oh, those guys look neat, add that one to the inhabited planet catalog"

They'd probably look at us (for food) the way most people look at food currently coming out of China. Polluted garbage.

or perhaps they'd look at us like wild beasts, ripe for cultivation in their factory farms.
