A Denver man who wants the city to be prepared for space aliens is proposing a commission to deal with the matter. Jeff Peckman says the 18-member commission would form a strategy "dealing with issues related to the presence of extraterrestrial beings on Earth." His proposal is slated to be discussed next week during a "review and comment" meeting. The assistant city attorney says he doesn't know what officials will ask about it. The 54-year-old Peckman also needs 4,000 signatures to get his proposal on the November ballot.
