UFOs, Chemtrails, and Aliens | Donald Prothero & Tim Callahan

UFOs. Aliens. Strange crop circles. The amazing alignment of the pyramids. Lines of clouds in the sky. The paranormal is alive and well...

In UFOs, Chemtrails, and Aliens, regular Skeptic contributors Donald Prothero and Tim Callahan explore why such demonstrably false beliefs thrive despite decades of education and scientific debunking.

Employing the ground rules of science and the standards of scientific evidence, they discuss a wide range of topics, including the reliability of eyewitness testimony, psychological research into why people want to believe in aliens and UFOs, and the role conspiratorial thinking plays in UFO culture.

They examine a variety of UFO sightings and describe the standards of evidence used to determine whether UFOs are actual alien spacecraft.

Finally, they consider our views of aliens and the strong cultural signals that provide the shapes and behaviors of these beings.
