Many skeptics have argued that there never has been any physical evidence that would show that UFOs are real. And yet, researchers and scientists from around the world have collected samples of soil and vegetation from the physical traces left behind by unusual objects of unknown origin.

One of the most famous cases of UFO landings occurred outside of Socorro, New Mexico, on April 24, 1964. Officer Lonnie Zamora came upon a landed craft which he first took to be an overturned car. Upon closer inspection, he noticed that the object was egg-shaped, white in color with an unusual red marking on its side. Standing next to it were two child-size occupants dressed in white overalls.

A smoldering bush and four rectangular indentations were found at the site.
