9. Dinosaurs Helped Build The Pyramids
The pyramids have long been the subject of a wild variety of conspiracy theories, but this one really takes the biscuit. A school in Malta, named the Accelerated Christian Academy, has a director that believes the dinosaurs were not only alive at the same time as humans, but also gave the Egyptians a hand (or claw) in building the pyramids.
Speaking of the theory, director of the institution Vince Fenech states quite clearly, "Of course the dinosaurs existed. It is mentioned in the Book of Job. They were used to help build the pyramids". Fortunately, Fenech claims that this particular theory isn't taught at his school, and it's only a "personal belief" of his. He does, however, teach that the universe is only 6,000 years old, so it's probably best not to send your child over to the institution just yet.
