First level characters are peons, nobodies. They don't have a story. It is up to you to forge a story through game-play. Your character's story is when you are tenth level (or some other advanced level) looking back on your adventuring career.
I remember creating a 3e character shortly after the edition premiered in 2000. The DM asked me if I wanted to create a back-story for him. I replied, "If he survives to about 5th level, I'll get back to you."
Well, that's one (common) approach. The other approach is to provide a detailed background right from the start. It's a matter of personal taste, really.
Two of my players have written several short stories about their 'adventures' before we actually started playing - however, they didn't start at first level (sic!).
Another player doesn't seem to care much and basically just reincarnates his original character all the time, changing only minor aspects of his background.
I find it difficult to imagine that even a first level character doesn't have anything interesting to write down, especially representatives of the long-living races. Noone lives in a vacuum; there'll be family, friends and maybe even enemies. Finally, every character should have a motivation for becoming an adventurer (unless developing the reason is part of the first adventure).
I don't mind if a character doesn't have any background at first level, but I do mind if the character doesn't have one at 10th level!
@ptolemy18: It seems your views on character creation aren't that different from mine after all

I, too, enjoy creating new characters a lot, even if their life expectancy isn't particularly high. That's why I am most often the DM; this allows me to try out different character concepts as often as I like.
But it still pains me to see a player's character die, when the player invested a lot of effort into developing the character. In the past I've simply used a higher starting level (2 or 3), but I'd prefer a system where the characters are stronger from the start.
