Lloyd Anthony Pye Jr., an American author and investigator of the paranormal, gained widespread recognition for his advocacy surrounding the Starchild skull. He fervently contended that it constituted evidence of a human-alien hybrid, despite subsequent DNA analysis confirming its origins as that of a human male. Pye also championed the belief in the existence of cryptic creatures like Bigfoot and proposed the theory of extraterrestrial involvement in human evolution.

   During the late 1990s, Pye acquired an unusually shaped skull from a couple in El Paso, Texas, positing it as potentially extraterrestrial in nature. Subsequent DNA tests, however, established its human male origins. Notably, American clinical neurologist Steven Novella asserted that the skull belonged to a child afflicted with hydrocephalus. In 2009, Pye showcased a replica of the skull during a lecture tour across Europe, including a presentation at the Leeds Exopolitics Expo.
