Betty Hill's Alien Book and The Adamski/Orthon Shoe Print

This is a reproduction of what Betty Hill said were symbols on a book she espied on the craft that allegedly abducted her and her husband Barney in 1961:

This is purportedly an imprint from the shoe of Orthon, the "man from Venus" who met with George Adamski in the Colorado Desert in 1952:

One can find similarities in both of the symbolic renderings.

What does this tell us about the alleged incidents?

That they were real alien contacts, from bona fide extraterrestrials, from the same place, using the same "language" or "writing"?

Or that delusional people tap in to similar aberrant mental configurations?

An investigation or study of the symbols provided by flying saucer (UFO) witnesses might provide a clue that is neurologically significant or extraterrestrially significant.

(I don't think it's the latter.)
