Unique UN jobs and response

From The Corner

When aliens darken our daytime sky with ships, Mazlan Othman will be on the case:

THE United Nations was set today to appoint an obscure Malaysian astrophysicist to act as Earth’s first contact for any aliens that may come visiting.

Mazlan Othman, the head of the UN's little-known Office for Outer Space Affairs (Unoosa), ... that ... the UN must be ready to coordinate humanity’s response to any “first contact”....

Professor Richard Crowther, an expert in space law and governance at the UK Space Agency and who leads British delegations to the UN on such matters, said: “Othman is absolutely the nearest thing we have to a ‘take me to your leader’ person.”

I'm not sure I understand that bit. Does this mean Othman will be presented as the leader of planet earth or will he ask the aliens if he can be taken to their leader?
Update: From my kind of reader:

Forgive a comment from your Constitutional Separation of Powers Guy:

What is up with the blithe (If not arrogant)  assumption  by UN pinheads that they have authority to speak for us to any space aliens who might arrive?  ...

The UN is in no way, under international law or the Constitution of the US, empowered and authorized to speak on behalf of any sovereign state especially the United States.  ...

More broadly, both the Constitution and the Declaration of Independence espouse and rely upon the classically liberal concept of government powers justly based on the consent of the governed (as even now we have repeated in principle in GOP Pledge to America): this is the overarching reason why the UN cannot deign to speak on our behalf or to enact any enforceable decisions or proclamations as far as people of the US are concerned.  As the lady in the “Lord of the Castle” scene in Monty Python’s Holy Grail said, “Well,  I didn’t vote for him.’

All the best,
