In your opinion what's the greatest human invention?

In my opinion,the greatest invention in the world are books.Just as a famous persom has said that books are the best teachers.that's true.During the long history of human beings,books have played an important part in communicating knowledge.And even today,millions of books are published in the world every year.If a knowledged person want to express some new idea,probably he will choose to write a book.On the other hand,the best way to broaden our horizens is reading books.Books have changed our lives,and they are influencing our lives now and maybe tomorrow.

Hello,franziska! In my opinion the greatest human invention is Electricity,by dint of which in the subsequent period other amazing inventions,radio,telephone,telegraph,television,computers,were made which made our life most pleasurable.the root of all inventions is electricity. if there is no electricity we can not manage a day even.thanx.

For me, I considered the invention of the printing press in Gutenberg is the greatest with the massive production of Bibles starts the new way in which man views his faith, man is being educated. I think the key on freedom of one's country anchors through publishing.

i think the most human invention is making fire coz thats what you start everything.

I think that the best invention of a humanity is a simply tool like a stick or rock on a stick that could be a spear, hammer, hatchet etc. Why? couse it gave us the opportunity to make so much other inventions. I think that it's older even from the wheel. The second most important invention for me is math.

i my opinion, it would be the telephone. well, actually telegraph. all the gadgets what we have now, computers, psp's, tv's and of course cellphones are as far as i know derived from the same principle used in a telegraph. so if the telegraph wasnt invented by Alexander Graham Bell we probably would have the iphones or if not, it could have been in a later time.

wheel can be greatest invention .but i think fire is the greatest invention coz it make us eat first time so i think fire will wiln the race

I think it is the computer! we can do so much with it. talk to family, shop, pay bills, make money ect.
