Cookies aren't sent to unrelated sites, so I don't see how they do "the first thing". Cookies are only sent back to the site that originally sent them. While it's possible for cooperating sites to arrange communication using cookies (e.g. a site that hosts banner ads, and the site whose pages contain the banners), a site (even the NSA) cannot simply examine all your other cookies to see where you've been.
