Somethings that are talked about in stories, but have no proof to back up claimes made, are called myths. Over time many myths have developed. A few of them have to do with sience and other school related stuff, but the ones I'm going to tackle have to do with creatures and animals. There are a veriety of mythical creatures, some most people have heard of like the bigfoot, and some not many people have heard of like the chupacabra (goat sucker). If you look deep enough on the Internet, you can find a lot of mythical creatures.
