The first two thirds of the 60-minute broadcast were presented as a series of simulated news bulletins, which suggested to many listeners that an actual alien invasion by Martians was currently in progress. Compounding the issue was the fact that the Mercury Theatre on the Air was a sustaining show (it ran without commercial breaks), adding to the program's realism. Although there were sensationalist accounts in the press about a supposed panic in response to the broadcast, the precise extent of listener response has been debated.
In the days following the adaptation, however, there was widespread outrage and panic by certain listeners, who had believed the events described in the program were real. The program's news-bulletin format was described as cruelly deceptive by some newspapers and public figures, leading to an outcry against the perpetrators of the broadcast. Despite these complaints, the episode secured Welles' fame as a dramatist.
There is no proof of alien visitation .... just funny pictures of funny objects that we know not what of caught on camera out there in space.
There is lots of it and not anything that is remotely indicative of aliens .... please read and comprehend.
