No kidding. There is actually a school that claims to do that:
Exopolitics Certificate - Entry level certification provides the core conceptual understanding so you have basic competency in writing about, researching or investigating exopolitical issues.
Galactic Diplomacy Certificate - Second level of certification provides both the conceptual skills and diplomatic training so you can practice citizen diplomacy in extraterrestrial affairs.
Exopolitics Diploma - Third level certification designed for those intending to teach or train others in exopolitics.
The tuition cost for each course (five), the Substantial Research Paper and the Advanced Instructor Training is $375 each. Students have the choice of paying at the start of each semester for the courses they intend to complete or can pay in advance the reduced rate of $1995 to cover all coursework tuition costs ($630 saving off total course cost of $2625).
And what is Exopolitics?
"Exopolitics is the study of the political relations between humanity and extraterrestrial civilizations."
Is this the big big scam school? Or is it credible enough? YOU be the judge. :)
