Ancestor's communication network!!

An American and a Russian archaeologist were bragging to Santa.

The Russian said that while digging an ancient ruin in Russia, he came across some thick cables; therefore he claimed that Russians had the telegraph system long before it was invented.

The American said that while digging a ruin in America he found thin cables. This indicated that his ancestors used telephones.

Now it was the turn of our great Santa. He said that while digging ruins in India, men could find nothing; no cables, no wires. It clearly proves that his ancestors used the most sophisticated wireless system.
