A humble explanation provided to Chiao’s reported sighting involves a fishing boat in which its bright lights were spotted by Chiao hundreds of miles below him. But many people are not satisfied with the explanation and believe that there are more possible interpretations of what the astronaut observed.
Many are certain that Chiao witnessed an intelligently controlled alien spacecraft. However, Chiao does not think so. He believes that there is no tangible evidence that can justify about the presence of extraterrestrials on Earth in present and in the past but he doesn’t rule the possibility out 100 percent. He said that he is open-minded and believes the existence of other life somewhere in the universe.
