What do aliens look like, and where do they come from?
Because we do not know for certain that UFOs are spacecraft, we cannot be sure aliens are visiting the earth from other planets. Many ufologists argue that there is enough evidence to show that UFOs are really spacecraft operated by intelligent aliens. Among the reports of encounters with aliens (Close Encounters of the Third Kind, or CE-3s), there is a wide variety of descriptions. Some witnesses describe beings who look very human. In fact, they say these aliens could easily blend into the crowd on any street in any city of the world. These types of aliens are sometimes called Nordics, because they most closely resemble the people living in northern Europe. Others report seeing short, gray beings with large, almond-shaped eyes, and large, bulbous heads. These aliens have been called Grays.
