"Professor Marvin H. Mills" is a self-published crank. His book is printed by iUniverse, a vanity publishing company. Mills also believes that the mosques in Spain were built by Phoenicians aided by survivors from Atlantis  We learn of the "Piri Reis map" that "It lead Ivar Zapp and George Erikson in Atlantis in America (1998) to assert that an awareness of Antartica was known to an advanced civilization at the end of the Ice Age." And, yes, the published version of this book really does spell the second word of that sentence with an "a". Mills is not a reliable source. He is self-published and his views are fringe.
