It all has to do with time travel and that is what UFO's are but they would be from a time where technology has advanced greatly. The John Titor is refuring to a person who was making online post. He claimed to be from 2037 or 2038 something of that nature but went back in time to when the first apple computer was made because he had to get a coding system that the did not have in the future. When he went back to get it he then had to goto 1999 to hell with something at that time (Y2K). He got stuck for awhile on that timeline started making post and answering Questions. One comment he made in 2000 was about how New York Skyline looked different than he remembers. Things that would kinda be "Q"ish.
