One Invention That Changed The World

What could be the invention which changed the world? Light bulb, glue, Trinitrotoluene(TNT), The circle, Money. Well, according to in me the invention of money changed the world because if money wasn't there then humans had to do a better system which wasn't as. After many appeared we had currency and the value of money to buy anything we want from the store. Money even was used to pay tax and buy tax and those. Now you see you go to the market and buy some Fish, the shop keeper says to give him 56 dollars and 3 Cents, and you just give the money to the shop keeper and then just go, but if money was not there, then you would have to give him something which he likes which could have been a difficult task because we don't know what the shop keeper likes and what can we give him and then the shop keeper may even scam you, Money is even used to make FRIENDSHIP among two countries because the first country will give the other country some money and then the other country will be happy and will take the money and then accept the other countries friend request, in short, it is like a friendship maker, now in many countries we have paper notes and coins which are Customized so that it matches with the following country and be a symbol of the country for foreigners and thus money is very useful for Humans in these days.
