In Intelligent Life in the Universe (1966) astrophysicists Iosif Shklovsky [Shklovskii] and Carl Sagan devote a chapter to the argument that scientists and historians should seriously consider the possibility that extraterrestrial contact occurred during recorded history; however, Shklovskii and Sagan stressed that these ideas were speculative and unproven. Shklovskii and Sagan argued that sub-lightspeed interstellar travel by extraterrestrial life was a certainty when considering technologies that were established or feasible in the late 1960s; that repeated instances of extraterrestrial visitation to Earth were plausible; and that pre-scientific narratives can offer a potentially reliable means of describing contact with aliens.

Furthermore, the icy stuff that collected on Methone's surface could even be more lightweight than that which lies beneath. It is possible that such fluffy, snowy, stuff can actually flow--at least over long periods of thousands to millions of years--thus filling in the tell-tale scars of impact craters.
Other authors make similar assertions. In Our Mysterious Spaceship Moon (Dell, 1975), author Don Wilson publishes the following conversation between the Eagle crew and Mission Control, presumably picked up by ham radio operators during a broadcast interruption attributed by NASA to an "overheated camera":
