If they were so advanced, presumably they would go to the trouble of learning to communicate with us before they arrived or announced themselves. If this were the case, we should probably just listen as we're at a fairly significant disadvantage and we have more to gain from them than them from us. In that case, I'd probably send the Aga Khan, Dalai Lama, a Pope and other religious leaders because they deal with this specific existential problem in a fairly in-depth way, and and billions of people will credibly listen to them. However, if the aliens just YOLO'd it and showed up, this sounds completely insane, but I'd send the head rider of the Spanish Riding School of Vienna or the Cadre Noir of France, as an advisor/translator because they have spent their entire lives cultivating the ability to listen, empathize, and develop sophisticated communications and relationships with beings that are non-human and completely alien to us, while also necessarily embodying human leadership characteristics people develop, and are therefore probably the only humans trustworthy to represent us to an alien species. Nuts, but we're way past nuts if this happened.
