The Origin of Zero

The articles I read really sparked something inside me. I never even thought that zero hadn't existed before. I just thought that it made thought up when all the other numbers were. But really it was invented by people as a place holder. And the people who invented it didn't really know what it was either.

I'm really not sure who invented the number '0'. Though both of the articles say that different people made it up, I think that you can never be sure. I mean, how do we know what people were thinking? We don't know what they knew, and if another civilization came up with the idea first.

I'm not sure how the whole world got the memo to agree to use the number '0', but I guess they did. Also, they originally came up with the idea as just a placeholder. It wasn't meant to be a number, actually. Which seems crazy to me, because I've only thought of it as a number.
