Can someone point me to where the "planetary origin" story is originating from? I have heard people talking about it, but I didn't recall picking up on anything like that from the narration at the Epcot Experience show. It sounded more like Alien Encounter where a fictitious alien race is hosting a World Showcase-like pavilion. And Rocket comes in.
While it's a bit of a stretch, I can see how a story about how our planetary system came to be could fit into Epcot's overall story. And where Rocket says, "That's boring - let me take you there." But, I didn't get that from what I remembered hearing.
