Well thats the thing see, there is only one planet currently available but its occupied. I thought about tilting it over and shaking it vigorously so all the people slide over to one side, but can't find a fulcrum or lever big enough.
Aliens could maybe take us somewhere else. There have been about 20,000 people a year visiting the 'upside-down' mountain pictured below in Bugerach, France. This is the place, according to some, where the aliens will rescue people before the world ends in 2012. They are expecting a lot of visitors in December. I'd like to check out some of the local hotel registers to see who has booked reservations around the 21st. Especially if they are being held with extraterresial credit cards (-3rd Bank of Venus, etc.)
But that is kinda a different crowd, and they probably don't have room for another 150 mil on the spectrum.
I myself don't think aliens have visited our planet. I mean I think there is a good chance of life elsewhere, but don't think interplanetary travel would be easy for anyone to do. And I don't see why aliens are going to be any super intelligent race that has solved all these incredibly difficult problems. They in all likelyhood are just another bunch of cocky animals like us, goof off, and probably make fart jokes too. No fart-joke race has ever been known to solve the technical problems of interplanetary travel.
Oh and Sylkat,
Flying Dinosaur eggs are about the size of a pretty big potato. If you need that down to centimeters let me know. P.S. I am getting a bit tired of having to go back and copy how you spelled perrydacktil, so am going to use the more conveinent circumlocation 'flying dinosaurs' from now on.
