That one is a lot more interesting, though it's basically just a map, which is atypical for flags.

The OP's flag is very abstract. Presumably, any other alien race also strives for unity and lives.

It's hard to create a better flag without actually knowing aliens and having some idea of commonalities and differences with humanity. Indeed, maybe we need a flag for humanity, not planet earth?

These would be the current candidates for humanity:

(BTW there is a flag for earth: http://static.news18.com/pix/2015/04/UN_flag.jpg )

I wasn't aware the UN actually had a flag for Earth; BTW, it seems they don't regard Antarctica as belonging to our planet...

It's not really the flag for earth. But it gets kinda close being official flag and having 193 member states out of 194(?).

Well, the exact number of countries is a very messy issue and the definition of what is a country tends to be "whatever other countries acknowledge to be one". This can be especially awkward if some of the other countries don't want to accept its status and the rest plays along because they have no incentive to get involved.

Not so atypical for recent flags:

The programmer in me can't help but think about the maintenance map-based flags incur with border changes.

I have similar reservations about the US flag. :)
