To Moneylovers,
- We do not need money. Simple trading would do the trick. In fact, our society would be much better off without it.

Duh
- Got to have glue people. i need to use 25 more characters....

Hmmmm.....
- I think a very important invention is the running water/plumbing system. Without it, we could not use toilets, showers,sinks,etc. as effectively.

Exteme Disagreement
- Our Saviour and Lord was not an invention. He is an all-powerful being that was and is and is to come. In other words, he just is. He always existed. There was no beginning and will be no end of Him.

isnt it obvious?
- seriously? the greatest invention in history is language! without it, no person could communicate to another and therfore, could not create other inventions that require the help of communications

The U-Net Global Wireless Broadband
- The U-Net is my favorite invention because it gives everyone in the world free satellite television and radio, and affordable phone and internet service, everywhere in the world-- and for less than any other service. It will soon replace most other communications.

The DYNAMO invented by Micheal Faraday
- The dynamo is and i think will remain the best device for generate surficient electricity and man can't do without electricy. You will agree with me that energy provided by coal power stations, gas power stations, dams, patrol and diesel engines, wind mills etc. must be passed through a dynamo if it is to be converted into electrical energy. Electric cells will have to be charged by already existing electrical energy before they could generate electricity and can't even provide electricity for commercial and industrial use. You can talk about solar panels but how reliable and how surficient can that generate electricity? No not for heating huge furnaces to melt metals like steel in factories 24/7. We just have to give the best invention to the DYNAMO but if anyone can invent a device that will create or destroy energy, it will be the best invention of ages becaus that is seen as an impossibilty by most intelligent scientist of all ages so work on that if you want to be the best invento

The Lightbulb
- Of course the lightbulb because we use lights the most every day!!

not a gadget, but language?
- Let's go back to the basics. No doubt computers and the Internet are huge, as huge as book printing (though probably not writing itself), but LANGUAGE. Don't forget that's a human invention, one that basically raised us above primate level. Could we even think sophisticatedly without language?

Microscopes. And the wheel.
- The wheel made just about all of this possible, which is why the wheel is the greatest; but the microscope (and by extension the telescope) has lead to hundreds of discoveries that have saved lives and harmed them, uncovered many of the 'secrets' of life, such as how it begins with a single egg, how infection begins and how we can stop it. If microscopes had never been invented and the things they've shown proven, more than half of the information in your science textbooks would simply disappear. (Unless your studying Earth Science. In which case, I empathize with you.)
