Debate: Wrestlemania as the Greatest thing ever created in Pro Wrestling?

[Emperor Smeat]

Lets say hypothetically pro wrestling disappears completely as a sport or form of entertainment, will Wrestlemania be considered the greatest idea or achievement in the history of pro wrestling or will some other idea/moment be thought of as bigger?

Its the only event in wrestling that attracts huge hype and crowds even from people who are not wrestling fans similar to the Superbowl for football and the World Cup for soccer.
