You can discover anything if you've never been there before. I discovered a great restaurant just the other day that had been there for years.
Finding anything that you dont know about is a discovery.
Haha, I voted you down on accident, I actually meant to vote it up. But I fucked it up. I thought I would leave it like that as proof that I am less than perfect. Hopefully that might dispel some of the myths :)
Said the natives...
We've not killed all the natives in Africa..... I'll get my gun.
Sure you can. It's a matter of perspective, the fact that the locals knew the continent existed was irrelevant to the Europeans, Europe didn't know it existed until it was discovered by their explorers.
Columbus was a douche
Discovery is learning something new. Continents have been discovered with millions of native on them.
