what will happen if internet doesn't exist today?

actually,i don't what 2 say.but 4 me,we knew that Internet was very IMPORTANT now days.all the things become faster by using Internet.for example,we used Internet to sending an official or business messages,paying tax or even shopping!!!IT is all IN our HANDS.so if there is no Internet,we can say that our work become SLOWER & not in progress....beside,we also are not able to send important data (4 example:about country defence)in progress so it means that we can not take an early action.
that is my first impression when i read the comment...
secondly,without Internet we also always have to waste our time,make a straight line 2 pay some tax or paying electrical bills or whateva...beside used to connect millions of business and government agencies,Internet also used by educational institution & individuals.
with Internet we are able to communicate with people all over the world with easy terms and low in cost...
in conclusions,Internet make the world become border less.so,if there if Internet does not exist we are not able 2 communicate with each other with the CHEAPEST & EASIESTmethod.......
