July 22, 2014 - The way David M. Jacobs sees it, aliens from outer space have been kidnapping humans for aeons and sexually molesting them to create human-alien hybrids that walk among us today undetected and will soon take over Earth.
He knows that sounds crazy.
But he long ago quit caring what people think of him. As director of the International Center for Abduction Research, Jacobs, 71, has made it his life's mission to investigate claims of extraterrestrial abduction.
"What I'm doing will either be an interesting but nonessential footnote to popular culture or the most important thing that's ever happened to humankind. I see it as the latter," said Jacobs, who's now working on his fifth book, tentatively titled The New People.
While most people might write off UFO believers as deluded, conspiracy-theorist kooks, Jacobs isn't your typical believer.
He was a tenured professor at Temple University, where he taught American history for 36 years before retiring in 2011. He's a married father of two who lives in a picturesque, 134-year-old Victorian just over the Philadelphia line, in Wyndmoor. He makes his case with well-reasoned, articulate explanations and applies a scholarly approach to his research, which he has shared in four books - printed by well-known and academic publishers.
Jacobs has interviewed about 150 people who say they've been abducted by aliens, the forgotten details of their cosmic kidnappings resurfacing in relaxation sessions the self-taught hypnotist does in his home.
Citing public polls, he estimates that aliens have abducted more than a million Americans.
He readily admits that the evidence of extraterrestrial life and body-snatching is "weak," muddied by an abundance of blurry photos and confabulation (phony or misinterpreted "memories").
Yet he insists evidence exists:
* Abductees independently report similar experiences and recall common details, such as the humanlike or insectlike appearance of aliens and their mission to breed.
Many abductees told Jacobs that aliens stared deeply into their eyes, sometimes touching foreheads, in a neurological scan that enabled them to harvest human sperm and eggs. Women frequently claimed that aliens impregnated them, removed the alien-human hybrid fetuses from their wombs and forced the women to nurse the hybrid babies.
* People are physically absent during the time they say they were abducted, Jacobs said. Some families even have reported loved ones missing or seen them vanish, he added.
* Abductees sometimes are taken in groups; strangers who never met on Earth recall each other from their deep-space experiences, Jacobs said.
* People return with unusual marks, injuries or scars - including scar tissue that formed overnight, "a biological impossibility that I have seen myself," he said.
