A UFO proponent once argued to me that Occam’s razor, which he defined as preferring the simplest explanation for any phenomenon, actually favors the theory that aliens are visiting the Earth. The presence of aliens could potentially explain cattle mutilations, crop circles, reports of sightings and abductions, and a host of other strange phenomena. Skeptics come up with a separate explanation for each of these things. One explanation—aliens—was far simpler, and therefore a good skeptic should accept claims of alien visitation.
