Keep your heads up for Abraham Lincoln impersonators!
The actor who played the "got a light" woodsman has had previous gigs as a Lincoln impersonator. Maybe his resemblance is no accident. Honest Abe did grow up in a log cabin, after all.
In the secret History the supposed contact between leaders and the Nordic types, who offered technology if the U.S. gave up nukes.

This meeting was in 55 so is this the deal.
