D.W. Pasulka, a professor of religious studies at the University of North Carolina, examines how belief in extraterrestrial intelligence functions as an emerging religious phenomenon. Her research took her from Vatican archives to secret aerospace facilities, interviewing scientists and Silicon Valley entrepreneurs who treat UFO encounters as genuine contact with nonhuman intelligence. Pasulka argues that the protocols of belief surrounding UFOs mirror those of traditional religions: sacred sites, conversion experiences, chosen witnesses, and interpretive communities that determine what counts as evidence. She profiles figures like Jacques Vallee, the computer scientist and UFO researcher who inspired the character in Close Encounters, and Tyler D., a pseudonymous aerospace executive who believes he has recovered extraterrestrial artifacts. The book traces how technological mediation--satellite imagery, digital enhancement, social media--transforms religious experience in ways that make UFO belief newly plausible for technically sophisticated people. Pasulka draws on her expertise in Catholic miracle traditions to show how UFO narratives borrow and modify religious frameworks even while presenting themselves as scientific. She does not adjudicate whether extraterrestrials exist but rather analyzes what belief in them reveals about contemporary spirituality and the boundaries between science and religion. The result is a portrait of belief in transition, capturing a moment when ancient patterns of religious experience find new technological expression.
