A video purportedly showing aliens has been shown to the press, the Denver Post reports.
The approximately three-minute-long video, in grainy black and white, appears to show a creature with big eyes looking through a window into a house, the Post said. But it was unclear if it was a puppet or an alien.
Jeff Peckman, who has proposed the city of Denver create an 18-member extraterrestrial affairs commission, screened the video for the media Friday at Metropolitan State College.
"This one looked very gentle and very innocent and youthful," Peckman told FOX News on Friday.
The video shows a white creature with a balloon-shaped head that pops up and down in a windowsill 8 feet above the ground, according to the Post.
Peckman said the head popped up on the windowsill four times, the face white with large black eyes that appeared to blink.
The video was taken on July 17, 2003, in Nebraska by Stan Romanek, according to Alejandro Rojas, the education director of the Mutual UFO Network, who spoke at Friday's press conference.
Rojas said Romanek set up the camera because he feared Peeping Toms were stalking his teen daughters, according to the Post.
Photographers and TV cameramen were not allowed to record images from the video at the press conference, the Post said.
Peckman did not release the video to FOX News.
"It's under agreement right now and negotiations are under way to create a documentary out of this for widespread use," Peckman said.
