Back in the 1960s, David Halperin was a teenage UFO investigator.
Later he became a professor of religious studies — his specialty, religious traditions of heavenly ascent.
From 1976 through 2000, David taught Jewish history in the Religious Studies Department at the University of North Carolina, Chapel Hill.
Now retired from teaching, he lives in North Carolina with his wife Rose. His first novel, "Journal of a UFO Investigator" was published in 2001.
Using the first known UFO abduction case, Barney and Betty Hill in 1961, Halperin explains his unique theory on the origin of UFO's. Looking to the skies may not be the correct course of action, according to Halperin. The answer may be much closer to all of us.
