What was the greatest invention? (actor, children, accident, people)

[redguard57]

Farming. I'll also second the person who said domestication of animals. Those two things are what underpin civilization, allow for specialization.

Without those two things, there'd be a few hundred thousand to a couple million of us scattered around worldwide still living as hunter-gatherers.

The wheel. Without the wheel, nothing else would be possible. BTW fire and electricity are discoveries, not inventions.

Fire was discovered, not invented, since fire is a natural process. I agree that fire is the winner. My vote for 1st runner up is language. Without language, rheumatologists and orthopods would have a lot fewer patients than they do now with all those neck and thumbaches from excessive texting, and then where would we be?
