If aliens came to our planet, they would probably go see Neil deGrasse Tyson because he is a planetary scientist. That is unless they came from Pluto.
Anyways, if they asked him to take them to his leader, which leader would he take them to? He would bring them to Comic-Con so that they could see people that look like them. Then he pondered if people on their planet dress up as humans at their comic conventions?
And now I am imagining what aliens look like if they dressed up as us. Who would they pick as the person they would want to look like? Probably, Kim Kardashian because they have wide middles like her. That, and she looks like one of them.
