I beg to disagree. The ordinary people in those circumstances died.
I would probably say I left a statement out, they were ordinary people, and an extraordinary event happened, and now they may be considered extraordinary people after the fact.
Besides, you missed my point. I was specifically questioning your definition of extraordinary. What do you need 'extraordinary' people by your definition, if extraordinary people by my definition are already doing extraordinary things. Why do you need 10th level characters anyway? What do you need to hold out for? Is it to have dramatic world changing events? Is it to have mass combat? Is it to fight terrifying monsters? Is it to be important within a community? What are you trying to achieve?
Extraordinary, is in my book, people who have been though a lot, or people who have worked hard to earn greatness. I use 10th level as an example because if you compare what a 10th level has to a st level, it's a great deal. A 1st level character is some guy off the streets, thrust into extraordinary circumstances, when they have survived them, then they can be extraordinary people. But not before.
Mechanically, also, it doesn't translate well, you can describe your character as extraordinarily as you want, but nothing in the game will demonstrate that until much later on.
I strongly suspect that a 6th level PC in my world is more extraordinary than a 10th or 12th level PC is in many other worlds. I know this is the case comparing my world to certain published settings where being a 12th level character qualifies you to be a shopkeeper, bartender, or yeoman farmer and the real movers and shakers of the world are 20th level or higher. In such a setting, a 10th level character is mundane, and it requires a 25th level character (or some such) to be extraordinary. It really doesn't matter what the numbers are. What matters is how numbers compare to other numbers. What matters is the character of the characters and whether they live in a dramatic, cinematic, epic scale world regardless of the numbers on the peice of paper that is the real world token of the character. Adding extra zeroes to the ends of numbers on that token doesn't inherently make the characters more extraordinary.
Of course if you change the scale you're going to get different results. The best trained fighter in a town of farmers can still be the worst trained fighter in a town of fighters. And yes, that's exactly my point, extraordinary is something you earn, and there are often people who have earned more than you.
Even though Superman was gifted with extraordinary powers, he still had to work hard to become an extraordinary person. And when on Krypton(or New Krypton) he was just plain old Ordinary Kal-El.
