DENVER -- A man who is pushing to create a task force to deal with space aliens said he has proof they exist and showed the video to the media Friday morning.

Denver resident Jeff Peckman believes the video is "irrefutable evidence" of alien visitation.

The black and white video he showed was shot by Stan Romanek in Nebraska in July 2003. Romanek said in a film clip that he thought there might have been a peeping tom peering through his window so he grabbed a video camera and started recording.

The bald, whitish "being" with an elliptical "head" is seen in the video peering just over a windowsill, blinking, looking around and then going down, out of view.

"It does have somewhat of an ET appearance as I recall, but the skin was much more smooth, not these deep old wrinkles. (It was ) very gentle looking, benevolent, kind of had a soft appearance to it," said Peckman, describing the video.

News crews were told to turn their cameras away so no video of the "being" can be shown in public until the film can be analyzed. The video clip will be included in an upcoming documentary but first has to be looked at by experts to confirm that it was not doctored.

Jerry Hufmann, a professional video producer and an instructor at Colorado Film School, said he believes that the alien video had not been altered in any way and the "being" did not look like a puppet or part of any special effects.

Peckman said extraterrestrials have visited earth frequently and the close encounters have been covered up by the U.S. government.

"According to one report, there are as many as 57 species, that have been documented by our own government, that have visited our planet," Peckman said.

Peckman is spearheading a Denver ballot initiative to create an 18-member Extraterrestrial Affairs Commission that would form a strategy "dealing with issues related to the presence of extraterrestrial beings on Earth" and how humans and aliens can peacefully coexist.

The 54-year-old needs 4,000 signatures to get the proposal on the ballot. The commission would cost $75,000 to form and maintain, Peckman said.

"We believe that the end result of all this information will ultimately lead to a higher quality of life, a cleaner planet, the availability of technology that will help us in multiple areas," Peckman said.

In the case of extraterrestrial contact, the United States government would be the governing authority, superseding local authorities, so it's not known what the city commission would accomplish. However, Peckman believes that the U.S. government is not doing enough.

Peckman sponsored a 2003 initiative that would require the city to implement stress-reduction techniques. That idea didn't garner enough support from voters.
