German scientists dug 50 metres underground and discovered small pieces of copper. After studying these pieces for a long time, Germany announced that the ancient Germans 25,000 years ago had a nationwide telephone network. Naturally, the British government was not that easily impressed. They ordered their own scientists to dig even deeper. 100 metres down, they found small pieces of glass, and they soon announced that the ancient Brits 35,000 years ago already had a nationwide fibre net. Israeli scientists were outraged. They dug 50, 100 and 200 metres underground, but found absolutely nothing……They concluded that the ancient Hebrews 55,000 years ago had cellular telephones.
