I like that theory. I don't know if I necessarily believe it, but it fascinates the hell out of me.
I began writing a story about a lost civilization like that a few months ago, actually. Not to self-pimp or anything, but I'll tell you a bit about it. There was a very advanced civilization that had a great nuclear war that destroyed absolutely everything and changed the environment of Earth forever. The temperature got colder, and food became scarce. There were people, scientists, who knew that their civilization was coming to end. They didn't know if humankind would survive, but just in case they did, the scientists wanted to prevent the future generations from ever befalling the same fate they did. So they carved specific pictoral, as well as basic written instructions and warnings on a series of hard stone tablets, and buried them in random locations all over the world. Thousands of years passed, and the number of humans in the world dwindled to just a few dozen at the very lowest point. All knowledge of the world that had once been was lost forever, buried deep under the glaciers that engulfed the earth. Around the end of the Ice Age, the human populations began to grow again, and start over from scratch. Some centuries later, one of the stone tablets was unearthed in Mesopotamia. The people who found it were convinced it was a sign from God and obeyed the instructions on it religiously. And the rest is history. Literally.
But anyway. You don't care.
