This is what we're up against, poor education. The first words spoken on a telephone are quite famous and easily Googled.But Church history is part of history. You can't have the American Revolution without its religious elements. In fact, you don't even have the colonies without those factors. You don't have people being brought out of the dark ages unless you have a Protestant Reformation. The first book ever printed on a press was a Bible. The first words spoken over a phone line were "What hath God wrought?". You don't have the dark ages without Catholicism. It's all intermingled.
The first telephone conversation in history was made in Boston, the U.S. between the inventor Alexander Graham Bell and his assistant Thomas Watson on March 10, 1876. "Mr. Watson, come here, I want to see you," said Bell into his experimental telephone to Watson who was in another room but out of earshot.
