That actually makes more sense...
Soo, at some point in our evolutionary history, we started getting smarter, and doing more smart stuff. But each time someone died, all their knowledge of how to do smart stuff went lost forever.
Soo, being smart monkeys, we decided to invent the word, and use it to teach our kids how to do the smart stuff we always used to do, soo they could learn it themselves, and expand on it, then passing that knowledge onto their children.
Then some dude got the brilliant idea of writing stuff down, because it's easier than remembering things.
