Alien Archaeology
Xenoarchaeology is a hypothetical form of archaeology that exists mainly in science fiction works concerned with the physical remains of past (but not necessarily extinct) alien life and cultures. It is not currently practiced by mainstream archaeologists, due to the obvious lack of examples.

Famous quotes containing the word alien:
“The Jew is neither a newcomer nor an alien in this country or on this continent; his Americanism is as original and ancient as that of any race or people with the exception of the American Indian and other aborigines. He came in the caravels of Columbus, and he knocked at the gates of New Amsterdam only thirty-five years after the Pilgrim Fathers stepped ashore on Plymouth Rock.”
—Oscar Solomon Straus (1850–1926)
