The parapsychologist Andrija Puharich met Geller in 1971 and endorsed him as a genuine psychic. Under hypnosis, Geller claimed he was sent to Earth by extraterrestrials from a spaceship 53,000 light years away. Geller later denied the space fantasy claims, but affirmed there "is a slight possibility that some of my energies do have extraterrestrial connection." Puharich also stated that Geller teleported a dog through the walls of his house. Science writer Martin Gardner wrote that since "no expert on fraud was there as an observer," nobody should take the claim seriously.
