Two archeologists had arranged to meet at a cafe
to share their latest discoveries.

"My team has made a discovery that is so incredible it's going to completely revolutionise our understanding of the history of technology!", one archeologist said to his colleague.

"We were digging underneath the ruins of a castle which was built one thousand years ago, and we found telephone wires under the ruins!!

That proves that the people who lived in that area were using telephones by the eleventh century!!"

"That's nothing", his colleague replied smugly. "We were digging under the ruins of a castle that was built two thousand years ago, and we found no telephone wires under the ruins!!!

That proves that the people who lived in that area were
Using Mobile Phones by the first century!!!"
