We heard you lol. It's clearly in the top 10. The question is if it's even at the highest spot or not.

Electricity

language is #1 period nothing could exist without it

"period"? What, are you some kind of dictator? Shouldn't we vote first lol.

One could argue about language, but it's impossible to not have existed and there for not a great discovery or something. If you want to know why we're able to speak then it's because of evolution. We have something in our brain that's called zone of brocca(I don't know the english word, so it's in my native language) and strottenhoofd(again in my native language)
That's why it was inevitable that we learned a language.

Language in general nothing can be achieved without it NOTHING...and yes Xxain loves dictating

games.

Pfft, we killed the Neanderthalensis and Homo Erectus before we learned a language. That's quite an achievement don't ya think? We killed of the smarter neanderthalensis, mwahahaha. We're really the most violent species the universe has ever known.

no we language in are dumb ass a rock days even if it was just grunts

^ I guess you still need to learn that oh so great achievement of yours as I couldn't understand a thing you just said.
