At the close of the episode Giorgio A. Tsoukalos made the comment: "The Christians are awaiting for the return of Jesus. The Jews are waiting for the return of the Messiah. The Islamic community is waiting for the return of Muhammad. The idea of this return did not originate with any of those religious figures, but it, in fact, originated with the promise by extraterrestrials that they would return in the future. " Muslims are not awaiting the return of the prophet Muhammad they are like Christians awaiting the return of Jesus the prophet known to Muslims as Isa. This a huge mistake on the history channel's part and the not the first time has it misrepresented the Islamic faith. There is not a single Muslim who believe in the return of the man known as Muhammad. Please issue a correction for this, for many people rely solely on media like the history channel for factual information. I would hope I'm the future your guest's comments are fact checked before bypassing editing.
