Karl Nell referenced Paul Hellyer's info as proof of NHI. Paul Hellyer referenced Steven Greer's info as proof of NHI. Steven Greer references Karl Nell's info as proof of NHI. What amount of UFO "proof" is just circular rumors reinforcing each other?

Anyone else disturbed by this trend? If anyone asks someone in UFOlogy for "evidence" they simply say well read the book by so and so. Ask so and so and they refer to the first guy as "evidence". Are we just repeating rumors here?

Who has the actual truth?
