Why can I create a bitcoin wallet offline and still have the public and private keys correspond?

Using the website bitaddress.org with my wifi turned off, I can create a bitcoin paper wallet. Did the specific wallet already exist before I "discovered" it? How do the public and private keys correspond? The website creates a random public key but how does it know how to create the correct private key?

    it won't...until you connect back to wifi and it autoupdates.

    after all, you cannot even USE the BitCoin offline...

    The algorithm that creates both keys is downloaded in full when you open the website. Why would it need to be online to create a key pair?

    Your question is based on a wrong assumption.
