Humans have considerably more ability to think through the logic of a decision. And as other commenters mentioned, the difference in the level of effort to go see a chimp in person versus the effort of sending a spacecraft across astronomical distances is huge. I don't agree with the form of the argument here either - "the aliens are so advanced that you can't possibly fathom their reasons." Or even, more charitably - "the aliens are so advanced that a trip to see humans is trivial." In either case, stating "they're so advanced that we can't possibly make sense of them" doesn't mean the question's not valid.
