ooo i change my answer...def. thongs, what would a girl do if there were no end to panty lines?

MONEY!

or the production line... or maybe prostitution.

According to Biography channel..the printing press was the most influential invention of all time.

Not doubting you...

But what good was the printing press until the alphabet was invented?

Hmm good point but would the alphabet be considered an invention or a natural progression/evolution of speaking?

I believe it would be proper to say "Joe Smith" is credited with inventing the alphabet.... for example.

There are hundreds of dirfferent ones that "work" differently.

You wouldn't "discover" the alphabet, and it couldn't "evolve" sonce someone decided the number of letter, vowels etc. and how they are used.


Never really thought about it till now.... but I'm going with the alphabet. :)

Really, if you put it that way then there would be no such thing as an "invention." For example, the chair was an invention, but one could argue that people needed to sit down, so they used rocks, but once they built shelter rocks were no longer practical, so the rock evolved into the chair. Doesn't make a whole lot of sense, the rock evolving into the chair. :)

Computers! :winkwink:

Mastering fire or speech.

50 Innovations: Including Fire

that's a pretty tough question.

you could say something like "computers" but what about everything that needed to be invented for a computer to work?

It is the internet. For the same reason the printing press was the most important invention of the last millenium. Information could be spread throughout the country in a matter of weeks, which was astonishing at the time.

and now the internet takes the place of print. we can see pictures of the other side of the world seconds after they are taken. We no longer hear about news that happened, we watch it happen.

the internet IS the most important invention of our time (also computers because we need them to connect to the internet)
