Where do you think the nearest space alien is?

... in the next cubicle over
... in the office of the boss
... you are married to it
... Area 51
... in a secret underwater base in the ocean
... at a base on the far side of the moon
... on Phobos, the moon of Mars
... near a star over by Alpha Centauri
... in Hollywood
... in an adjacent dimension
... in your own head :-)
