Knowledge

So, knowing that we don't know something is the first step to knowing it? But how do I know what I know that I don't know? By knowing? And learning from others to receive knowledge?
But then what if I come across something that no one knows? If I can't learn from others to create knowledge, I will want to learn from nature, but what if I don't notice it because I don't know what it looks and feels like? And if I am able to notice it, doesn't it mean that I already knew it somewhere in my mind? Did I just create knowledge out of the lack of it?
Or did I just connect two dots? It is like my mind chose the right-fitting magnets to snap them with each other to create a new system. But then if we call the old magnets knowledge, what is this new thing? Isn't it the void, the very void that knowledge fears?
