You would know nothing if you weren't taught by your teaches so I can speak for you. you leaned something that was new to you but it already existed awaiting your discovery.
Really? Are you sure of that? This gets into some pretty deep philosophy of mathematics.
God said "there's nothing new under the heavens, all things continue as they have from the beginning" This means nothing new will ever be discovered, God already created everything that exists and nothing new will be created.
There's no new knowledge in the universe, it's only new to those who stumble upon it or discover it while looking for something new.
That's what it means to be new knowledge: it's the first time someone has 'stumbled on it or discovered it'. If nobody else discovered it, it is new.
