‘800-year-old mobile phone’ that was left behind by Aliens

Is this a ‘800-year-old mobile phone’ that was left behind by Aliens? No, it’s just a hoax

Considering that mobile phones started coming into the market in the 1980s, the claims made by conspiracy theorists that an ‘800-year-old mobile phone’ was left behind by ALIENS in Austria certainly sound absurd.

A YouTube video has emerged which claims to show an 800-year old artefact that appears similar to a Nokia mobile phone, with a screen, control keys, and 12 keys with Cuneiform symbols.
