  1. Question

    How can a person of logic discount the ufo phenomenon--with its unending flow of credible eyewitness accounts, government documents, and photographs of alien visitations and sightings--as a subject without evidence? Afterall, Nasa scientists categorically take many assumptions about our universe as truth, for which they yet have no physical evidence.

    disagree with both of your premises. (1) There are no credible eyewitness accounts, documents, photographs etc. that suggest "ufos" are alien spacecraft. (2) Scientists, whether NASA or otherwise, do not make categorical assumptions for which they have no evidence. If conclusions are not based on evidence (observations or experiments), then they are not science. UFO stories may be entertaining, but they do not meet the standards of science. David Morrison
