Not to mention, the effort and price of a trip to America was WAY smaller than colonizing the Moon, remember the Vikings did it too, with their inflatable boats... Read your freaking history books, but I already said that.... not to mention they were looking for a faster way to the East, they were discovering the unknown. (so the analogy fails on so many levels)There is nothing interesting or unknown on the Moon..
