A piece of footage from 1938 has people convinced time travel exists after a woman was spotted "chatting on a mobile phone''. In the film clip, a group of people can be seen walking towards the camera with a woman holding an object to her head in among them.
The woman seemingly looks to be chatting with the object up against her ear in the clip. Theorists believe the object she is captured talking into is a mobile phone, decades before the device was invented, reports the Mirror.
In the clip, the woman, donning a 1930's style dress, is seemingly chatting in amongst a crowd of people with the object pressed up against the side of her head in one hand. She then seems to take it down and away from her ear as the clip ends.
