We see today how records can be lost on purpose for various reasons, and it's easy to conclude that a lot of our past records were hidden similarly. The physical evidence on the planet rarely matches up with the official story on every continent, so a lot of information is obviously missing from our history. The remaining megalithic structures almost always tell a story that's more interesting than the one on the historical plaque. It's kind of a thrill to have my idea of history change every minute as I see the curious details of old paintings along with the unexplained evidence that still scatters the planet.
