A peice of aluminium dating back 300 million years has been found by a man while lighting a fire at home. The aluminium, which is several centimetres long and shaped like a gear tooth, was found stuck to a piece of coal.
Scientisits, who have dated the artifact found in Russia, say it could not have been created by nature.
The object is 98% aluminium and 2% magnesium and while aluminium very rarely exists in nature in such pure form, the technology required to shape such an object would not have been invented until millions of years after the estimated manufacture date. Some call it evidence of an alien race.
Scientists have downplayed the idea while conducting further tests.
