In your opinion, what has been the greatest invention?

Farming - probably an accident, or maybe pasturization (accident right?).

The pogo stick...

Language.

God

War

writing?

hmmmmmm are you sure you don't wanna change that to Computer Games? :D

Ouch.. ! lol

I would say that electricity is the greatest invention of the modern age. Without it we couldn't have any of the modern marvels like the Ipod or other necessities.
God? An invention made out of demand. We demand a reason for supply and out of boredom we supply a great demand for reason. Or just the fact that there needs to be a name given to the great unknown. Going off in that direction one might then conjecture that the first word would be the hypothetical "God" or in the general Jewish community G-- or in math X. Instead of changing pitches every other vocalization we focus ourselves in on the one as to say "the thing we don't know". So, language? Ay, the first invention of life so perhaps the greatest one to create.
Language...vocal language or just communication? The first time you make eye contact to realize that there is someone else in your existence is an invention of thought, no? One must then realize and create that concept of a person in the world.
The best invention is boring, the worst, though, that is another topic.

Beer?

The written language because if we couldn't describe how to make something then how would other be able to make anything.

Language wasn't an invention (a language expert should know that) but a development.
Big difference..
Otherwise the great inventions/discoveries are:

making fire,wheel, writing,glass, steel,printing, vaccination and electricity...

human rights

Oh boy, that is just silly. There is no such a thing as universal human rights. Every human deserves as much right as they can fight for...

magnetic perpetual motion machines.

I would say that electricity is the greatest invention of the modern age.

but electricity is not an invention, is it? it's a discovery, like gravity.

oh i get it... the use of electricity is an invention.

You x

me? thanks, but i'm not an invention...

Lol No, not you, but Nicnac (shes my fiancee)

Language wasn't an invention (a language expert should know that) but a development.Language is a technology, like farming, animal husbandry, metallurgy, etc. But I also maintain that we invented it. It was not something natural that we discovered and learned how to use, like metallurgy.but electricity is not an invention, is it? it's a discovery, like gravity.Electricity is a technology. Gravity is not really, since we haven't exactly harnessed its power.oh i get it... the use of electricity is an invention.There ya go. The use of something we find in nature can be a technology. Learning how to use it might qualify as an invention, but I'll leave that question open. Nonetheless, I don't believe that an invention has to be a physical object. Language is a tool and we invented it.

"Language wasn't an invention (a language expert should know that) but a development"

I'd disagree. I would think that written language was invented to make use of what the words were that were being said. Without a way to pass on information without losing anything would have to be done in another way other than speech. I would deduce then written language had to be invented in order to relay the speech into characters somehow.

The written language because if we couldn't describe how to make something then how would other be able to make anything.

The description comes last in the process. Imagination, materials, methodology, manufacture and "what shall we call it ? "
