After having dug to a depth of 10 feet last year, French scientists found traces of copper wire dating back 200 years and came to the conclusion that their ancestors already had a telephone network more than 150 years ago.
Not to be outdone by the French: in the weeks that followed, American archaeologists dug to a depth of 20 feet before finding traces of copper wire. Shortly afterwards, they published an article in the New York Times saying : "American archaeologists, having found traces of 250-year-old copper wire, have concluded that their ancestors already had an advanced high-tech communications network 50 years earlier than the French."
A few weeks later, ‘The British Archaeological Society of Northern England’ reported the following: "After digging down to a depth of 33 feet in the Skipton area of North Yorkshire in 2011, Charlie Hardcastle, a self-taught local amateur archaeologist, reported that he had found absolutely ****** all. Charlie has therefore concluded that 250 years ago, Britain had already gone wireless."
