This is almost amusingly irrelevant--if contact is actually made with an alien intelligence and this guy tries to step up and say "I'm in charge of this", there's no doubt someone more powerful would try and take over.
Simply because for the next few hundred years, they will have to have come to us, which immediately places them in the position of power. Yet, (if) we become highly mobile in space and find other life, we could easily be the ones in power.
