This is not a book of facts; it's a book of 'facts'. Should you finish it believing we became the planet's dominant species because predators found us too smelly to eat; or that the living bloodline of Christ is a family of Japanese garlic farmers - well, that's on you.Why are we here? Do ghosts exist? Did life on Earth begin after a badly tidied-up picnic? Was it just an iceberg that sank the Titanic? Are authors stealing their plotlines from the future? Will we ever talk to animals? And why, when you're in the shower, does the shower curtain always billow in towards you?

We don't know the answers to any of these questions. But don't worry, no matter what questions you have, you can bet on the fact that there is someone (or something) out there, investigating it on your behalf.
