The Oldest Building on Earth

The Tim Traveler is looking for the oldest surviving building on earth. First, you have to define what you mean by "building," and then you have to define what you mean by "surviving." There could be any number of old buildings to top the list, depending on how you define those terms. Which is good, because that means we get to learn about several very old structures in this video. Tim has qualifiers that are different from Wikipedia's list. (via Digg)
