Hi,

Recently it occurred to me to wonder what is the latest date in Earth
history when an extraterrestrial visit (a non-clandestine visit,
i.e.) could have occurred without having been recognized as such?

In asking the question, I am, of course, assuming that prior to some
date (now passed) an extraterrestrial appearing openly, to an
individual or in a community, would be explained as some kind of
supernatural being or simply a rare form of sentient but indigenous
life.

Naturally, I'm also assuming these etraterrestrials could not be
mistaken for or somehow pass as humans themselves.


Any ideas?

What makes you think that a visit from an alien today would be recognised as
such anywhere on earth?
