They think there is nothing special about them. They are not the megalithic remains of magical Bronze Age European "settlers" who ventured to the Americas in the second millennium BCE. And they aren't Phoenician, despite some dubious "inscriptions." And they aren't Atlantis. Their similarities to ancient megaliths are coincidence at best, and mischievous antiquarian forgery at worst.

"The whole point of having a specialized science such as archaeology is that we've determined certain methods of figuring out how we know what we know," says Runnels. "If you've got a Bronze Age site in, say, Great Britain, near Stonehenge, you're going to find pottery, tools, evidence of burials, and hearths. You're going to find artifacts of bronze, tin, copper, gold, and silver, and they'll have distinctive forms that are easily recognized, like this one." Runnels places a weathered bronze knife -- found in England and traced to the Bronze Age -- on his desk. "They haven't found anything like this. I'm just an old-fashioned empirical archaeologist. I want to see evidence."

The idea of an ancient, forgotten era of colonization in America was first popularized in 1835 by a book entitled American Antiquities, by Josiah Priest, who Runnels calls a "crackpot." His claims, dismissed by archaeologists, include, among other things, the ruins of a Roman fort in Marietta, Ga., and evidence that American Indians are descended from the Israelites. Over the next century, rumors spread about many sites in the United States.

Like many crackpot theories, this one enjoyed a "second wave" of infection across the land thanks to the early internet. This ridiculous dossier is a great example of a misinformed guy gone gone wrong, and this sort of thing should not be hosted on a respectable university's edu domain (in my not-so-humble opinion). This person seems (seemed?) otherwise ordinary.
