Since it seems an increasing number of my readers are interested in diffusionism and (presumably) real archaeological cultures, rather than the complete fantasy of aliens, I thought I would share a little bit about the archaeology of settlement.
The great thing about living atop a Victorian dump as a kid was that all sorts of weird things would erupt from the unsettled ground, and you couldn’t dig a hole or plant a tree without turning up some remnant of the past. Usually it was just broken pieces of glass, rusty metal, or shards of china. But sometimes it was more interesting. I once found a complete blue-painted metal coffee pot, barely rusted; and one time, after a storm, a large sink hole in a neighbor’s yard revealed the rusted remains of an early automobile. Too big to move, it was quickly reburied and is still down there even today. Far too often the roots of trees and bushes would churn up clam shells, which my father attributed to former residents’ long-ago clam bakes. Much, much later I would learn their true—and disgusting—purpose. The Victorians used clam shells to clean themselves before the invention of toilet paper.
From the artifacts that bubbled up from the earth, a picture of the daily life of people living around 1890-1910 emerged in a way that textbooks rarely illustrated. But the dump beneath my childhood home was no anomaly; everywhere that people live, piles of trash invariable arise. Archaeologists use the trash heaps—middens—created by long ago cultures to learn about how they lived, what they ate, and the tools they used.
Alternative archaeologists make grand claims about settlements in the United States of cultures from all over the world (funny, isn’t it, that they never seem to look for Hebrews, Romans, or Atlanteans in sub-Saharan Africa, southeast Asia, or Polynesia), and ancient astronaut speculators imagine aliens living and working alongside, or lording over, humans. Yet where is the trash? Do we really expect that the aliens never dropped a screw, or broke a laser-blaster? How is that Romans, Celts, Irish, British, Gauls, Hebrews, Phoenicians, Africans, Indians (from India), Atlanteans, Muvians, Lemurians, and more all managed to live in North America, colonize it, and interact with its people without leaving behind a single piece of trash with the markers of their cultures. We are expected to believe America is lousy with Old World cultural influence, but somehow all that survived were a few luxury artifacts—swords, inscribed stones, crosses, etc.—and absolutely no garbage, no assemblages of artifacts in the style of the Old World, nothing.
