What religion would best represent Earth?

Watched “Contact” with Jodi Foster, as an agnostic scientist. I’d seen it once before, but didn’t really pick up on the religious thing. They built some sort of space travel pod based on instructions from aliens. Jodi Foster lost her chance to be the “pilot” because she was an agnostic.

Someone made the argument along the lines that 95% of the people on earth believe in a supernatural being and why would we want to send someone who didn’t represent the majority of people on Earth?

Of course, the assumption was that it needed to be a Christian, which was really a stupid argument, IMO. Out of all the people on Earth, 33% claim Christianity, which leaves 67% of the rest of the entire population either claiming a different God or no God at all.

So assuming religion was a requirement, what one religion would best represent Earth?

(I got tickled when Jody Foster told her love interest, a very sexy, non-celibate, religious leader named Matthew McConaughey, that when she was a kid her dad would drop her off at Sunday school. She annoyed them with comments and questions like, “So, Cain killed off 25% of the earth’s population, then got married. Where did Mrs. Cain come from?” Indeed! :)
