Noah claimed the clip showed Las Vegas in the distant future, and showed several flying aircraft above a city, while he suggeste the lager vehicles could bt the busses of the future.

The background showed a city skyline, with low skyscrapers and rounded buildings, while the narrator can be heard suggesting the pink sky was caused by the amount of CO2 in the atmosphere.

The video was slammed by viewers, with some critics saying it was the ''worst CGI'' they'd seen.

Another commenter wrote: ''That video was absolutely fake. Nice cgi.''

However, Noah has stuck by his claims and said he ''didn't care what others think''.

He said: ''I know it's real. I simply want to spread my story.''
