Telecommunication System …!

German scientists dug 50 meters 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 nation wide telephone network.

Naturally, the British government was not that easily impressed.
They ordered their own scientists to dig even deeper. 100 meters
down, they found small pieces of glass, and they soon announced
that the ancient Brits 35,000 years ago already had a nation
wide fiber net.

Irani scientists were outraged. They dug 50, 100 and 200 meters
underground, but found absolutely nothing.

They concluded that the ancient  Persian 55,000 years ago had
cellular telephones !!
