I noticed this morning an office next door to a doctor’s office I was visiting. It’s called “The Conference of Major Superiors of Men.” So the alien are so convinced that they can conquer mankind that they rent offices for their planning and make no effort to hide it from mankind. Furthermore, the plural indicates that there are several, perhaps a vast number, of alien races that have decided to conquer mankind. Apparently they are deciding which race gets each continent or country or whatever.
You misunderstood. It actually is being rented by human women. 
Lex Luthor would still get Australia.
You got me curious, so I went a-Googling. Apparently, they’re a religious organization of some sort. Didn’t dig deep.
The Conference of Major Superiors of Men (CMSM) is the pontifically recognized national representative organization serving leaders of men’s religious congregations, monastic communities, and religious institutes in the United States.
CMSM is the common voice and the primary common resource for its members, who represent more than 200 monastic communities and provinces that include over 16,000+ Catholic religious-order priests and brothers.
CMSM was established on Sept. 27, 1956 following a request of Pope Pius XII for religious men and women to form national associations. This national representatives was canonically established by decree of the Sacred Congregation for Religious and Secular Institutes on Dec. 15, 1959.
What does Otis get?
The space elevator … 
That’s what they want you to think it is. Visit the place yourself. Be sure to have someone outside the door who is pointing a camera at you as you disappear into nothingness as you walk into the office and see the aliens. Be sure to have someone even further from the door who is pointing a camera at that person as they disappear into nothingness. Have someone pointing a camera at them, and someone pointing a camera at them, and so on for a line of hundreds of people. If mankind is lucky, they won’t be able to make all of them disappear.
So it’s a labor union for Monks, Priests, and other professional praying people?
Narrower than that – an association of leaders in those fields, and apparently limited to Roman Catholics (unsure about this). Monastic abbots, bishops and archbishops, and some others. Maybe ordained (?) deans/presidents of Catholic colleges, say, would be included. Maybe ordained Catholic clinic/hospital/nursing home directors.
Do they have an official cookbook yet?
They do. But it costs an arm and a leg.
Otisville.
At that he’s lucky. Ms Tessmacher gets the glowing remains of Hackensack
– points to recent actions in Russia, South Korea, Argentina, USA, France etc etc etc, not to mention our global climatic issues –
Really, I don’t think they’re wrong. We’re on the path to some really impressive self-imposed destruction, makes more sense to have a local office to periodically update the home office and call in the pest extermination squad once we finish subjugating ourselves.
– points to the above world rulers going insane again –
I for one welcome our new Alien Overlords! Come quick, because a totalitarian rule from a superior (pers the signage) alien species beats being ruled by the most vicious bigots the USA has to offer!
Of course, maybe they are aliens with low self-esteem, and are just trying to talk up a good game! I mean, really, if you can travel space at a speed making conquest viable, they could just wipe us out effortlessly by dropping rocks on us. Maybe they are having team-builders and chanting:
“I’m good enough, I’m smart enough, and dog gone it people like me.”
I recall a sorta wacky CT-ish acquaintance back around 2003 recommending to me a book dating from the 1980s-1990s that posited that all of humanity’s real problems are caused by meddlesome aliens who do it for teh lulz. We humans would all get along great if only the aliens didn’t keep stirring shit and influencing people to become despots or to back despots. or otherwise act all stupid.
200-ish pages of pure crackpottery nonsense. But the author(s) were sure True Believers of their own bullshit. Or so they seemed. Wish I could remember more about the book’s title or author to give a usable cite.
It reminds me of an old '60s era SciFi book I read and enjoyed back during my golden age.
There are similarities to current events.
I counter with the much more “real” to me movie, The World’s End where [major spoiler!!!] the muti-alien interplanetary society is desperately working to improve Earth (technology wise) and get us to all just behave like civilized sophonts only to find we’re so damn bloody-minded and self-determined (not in a good way) that they constantly have to replace us to get reasonable behavior.
Ending Spoiler:
Due to the actions of the protagonists, they eventually realize that it’ll never work, and certainly not worth their efforts to the greater good. So they say F**k it and leave, taking much of the last 50+ years of technological development with them, leaving us in a different sort of post-technological hellhole
Would it be better or worse if the aliens announced that they had come to Earth To Serve Mankind?
"Don’t go! We translated the book!
It’s a tennis manual!"
Fault! 
Curiously enough, their web site, cmsm dot org, is blocked by my employer’s firewall. So apparently there actually is something they do not want us to know.
