e Some persons nevertheless believe that UFOS are extraterrestrial spacecraft, even though no scientifically valid evidence supports that belief. The possibility of extraterrestrial civilizations is not the stumbling block; most scientists grant that intelligent life may well exist elsewhere in the universe. a fully convincing UFO photograph of a craftlike object has yet to be taken however and the scientific method requires that highly speculative explanations should not be adopted unless all of the more ordinary explanations can be ruled out

e UFO enthusiasts persist, however, and some persons even claim to have been abducted and taken aboard UFOS.(a close encounter of the third kind is UFo terminology for an alleged encounter between humans and visitors from outer space )No one has produced scientifically acceptable proof of these claims
