Look what I've found!

You can't "discover" something which is already there.  At least this is the basis on which Australian aborigines are objecting to statues of Captain Cook which describe him as the "discoverer" of Australia. And of course that's right - you could equally argue that Christopher Columbus did not discover America and so on.  But think about it - in order to discover anything it has to be already there in order to be discovered.   So it's all a bit silly really when you think about it.
