At the start of the Mr. Bean live action show, it shows Mr. Bean falling from the sky in the middle of London, and this has sparked many debates with fans if Mr. Bean is actually an alien, which is also an explanation to why he acts so odd. Another explanation stated that Mr. Bean is indeed human and used to behave normally until he was abducted by aliens and left mentally altered. This would explain the fact he is employed and owns a car and a house, and is engaged in a relationship with a woman with normal behavior despite his odd mannerisms.
The original intent of him beaming down from a light ray with the choir of singing may have really meant that he was being sent down from the Heavens above. Mr. Bean is confirmed as an alien in 'Double Trouble', the last episode of Mr. Bean The Animated Series, in this episode there is a UFO full of Mr. Bean clones that had dropped down Mr. Bean onto planet Earth many years ago and had reunited with him, but when they come to take him home, they see that his girlfriend Irma Gobb looks sad without him so they decide to keep him on Earth and erase Irma's memory. As Mr. Bean's people depart from Earth, Bean vows that he will meet them again someday.
