Why do we say Hello when answering the phone?

In this video, I've talked about why do we answer a phone/call saying "Hello" Who came up with the idea of saying Hello in the first place not what you think?

And the myth that Alexander Graham Bell's girlfriend/wife's name was Hello and he called her first saying hello and it became the ritual since then,

Thomas Alva Edison also worked on a telephone and he greatly improved Graham Bell's telephone but why no one knows about it?

Why Alexander Graham Bell didn't want people to use the word "Hello" as a greeting!

I break everything into this video I hope you like it, if you do then do Subscribe because I answer questions you don't have/ask.
