While you can easily tell that most of the things are just silly rumors, like the Jersey Devil, the time periods have holes in them. For example, in 1909, everyone figured it was okay to smoke. And drink a lot. Therefore the only reason it had any "sightings" is probably because a few people walked outside late at night, saw a bat, and freaked. But I must admit it is wonderful for entertainment. Also, ancient Egyptians built the pyramids, they were obsessed with the stars, but not from them. They aligned the pyramids up with the center of all of the stars. And yes, while they havent found "movie mummies" in them, they have found bodies. One body in each pyramid. Each pharaoh wanted one better than the last. Then the people said no more, and they started to put them in a trench, where no grave robbers could find them. No offense, but you need to check some of the "facts" in the app.
