I almost fell out of my chair laughing when I read this question. Not because of the question itself, but because it contains a kernel of truth. The short answer is no, both the AFC and NFC are conferences in the NFL, with equal status. But for the last several years, the AFC has proven to be the superior conference. The NFC has won the Super Bowl only 3 times since 1997.
However, the NFC and AFC used to be two seperate leagues, called the NFL and AFL, respectively. The leagues were in competition with each other, and the NFL, which was the original league, was considered far superior. Starting in 1967, the best team from both leagues played each other in an annual game that would eventually be called the Super Bowl. The leagues officially merged together in 1970 under the original National Football League's name, and formed two conferences. The original NFL teams were put in the NFC, and the teams that were in the AFL, were put in the AFC. (There may have been a team or two that had to switch to even things out, I'm not sure.)
